A Comprehensive Review of Artificial Intelligence and Machine Learning in Control Theory

Abstract: Traditional control methods, such as proportional-integral-derivative (PID) controllers and linear-quadratic regulators (LQRs), have proven effective for linear and well-modeled systems. However, these methods often perform poorly in nonlinear, complex and dynamic environments. The paper aims to investigate the modern control systems by integrating artificial intelligence (AI) techniques, such as machine learning (ML), reinforcement learning (RL), deep learning, and fuzzy logic, to enhance their adaptive, robust, and predictive capabilities. And it reviews the literature and analyzes AI integration in control systems. The proposed strategies include supervised learning for trajectory optimization and fault detection, reinforcement learning for optimal control in dynamic environments, neural networks for complex nonlinear function approximation, and fuzzy logic for handling uncertainty and imprecise inputs. AI techniques significantly enhance the ability to tackle nonlinear problems and dynamic changes, demonstrating superior performance in applications like self-driving cars adapting to various road conditions and optimal energy distribution in smart grids. Despite the challenges of computational complexity, scalability, and the safety and reliability in the implementation of interpretable AI models, this paper suggests that hybrid approaches combining traditional control and AI techniques, along with the evolution of interpretable AI and convergence with quantum control, hold great promise for advancing AI-driven control systems.

Research of Options for Constructing Information Management Systems Based on Network Models of Queuing Systems

The use of information management systems (IMSs) for the management of technical facilities is currently one of the directions for further improvement and increase in the effectiveness of the use of technical facilities in solving their target tasks. The existing modern IMSs are a set of hardware and software tools designed for collecting, processing and storing information and management. In the presence of a large amount of information and contradictory factors affecting the quality of management, making informed and timely decisions in the management process is impossible without the use of IMSs. The IMSs currently being developed are, for the most part, specialized systems and are designed to solve specific tasks. In this regard, the development and design of IMSs should be carried out taking into account the relationship with the target indicators and features of the management facilities, the results of a comprehensive analysis of information about the IMS elements in the process of functioning, and structural and algorithmic parameters that affect performance indicators. The use of mathematical models for the study of options for the construction of an IMS is the basis for the design and development of devices and subsystems of an IMS. The IMS models currently being developed make it possible to conduct research for single-stage management processes with the presence of similar service facilities in the system. At the same time, modern technical facilities and control systems are complex complexes with cyclically repeating control processes of various types of means. As a rule, such complexes have a set of parallel operating devices (control channels) that provide control of different types of objects at various stages of information processing. In this case, the structure of the IMS must be represented as a multiphase multichannel technical system in which the process of simultaneous management of several objects of various types takes place. In this regard, the purpose of the article is to develop a mathematical model of an IMS with two phases of management and the presence of an arbitrary number of serviced different types of management facilities. The basis of the model is a multiphase CFR network model with a limited waiting time for an application in the service queue. The study on the model allows choosing an option for building an IMS, in particular, choosing the optimal number of control channels for various types of objects according to the criterion of optimality and restrictions on the cost and time of management. An algorithm for selecting an option for building an IMS has been developed, and an example of calculating the number of control channels for managing three types of objects is given.

Adaptive fault-tolerant containment control for heterogeneous uncertain nonlinear multi-agent systems under actuator faults

As modern control systems involve a growing number of actuators, the consequent number of faults occurrence, which may deteriorate the closed-loop system performance, is increasing. Focusing on the containment control problem of generic nonlinear high-order heterogeneous uncertain Multi-Agent Systems, this study proposes a novel distributed adaptive fault-tolerant Proportional-Integral-Derivative control protocol to improve the reliability and the resilience of the whole networked systems against actuator failures. The Lyapunov theory, combined with the Barbalat lemma, provides the design of suitable adaptive mechanisms that adjust the PID control actions to ensure the asymptotic convergence of the closed-loop containment errors for the overall network, hence implying the convergence of each agent state toward the convex region shaped by the multiple leaders, despite the occurrence of actuators faults. The fulfillment of the fault-tolerant containment objective is ensured by requiring a lower computational burden with respect to alternative solutions, hence resulting in more attractive for wider practical engineering applications. Numerical simulation results, also including a comparison analysis with a state-of-the-art controller, corroborate the efficiency and the advantages of the proposed distributed PID controller.

Intelligent Rapid Asexual Propagation Technology—A Novel Aeroponics Propagation Approach

Various rapid propagation strategies have been discovered, which has facilitated large-scale plant reproduction and cultivar development. These methods, in many plant species, are used to rapidly generate large quantities (900 mini-tubers/m2) of high-quality propagule (free from contamination) at a relatively low cost in a small space. They are also used for plant preservation. This review article aims to provide potential applications for regeneration and clonal propagation. Plant propagation using advanced agrotechnology, such as aeroponics, is becoming increasingly popular among academics and industrialists. The advancement of asexual aeroponic propagation has been achieved through advancements in monitoring and control systems using IoT and smart sensor technology. New sensor technology systems have gained substantial interest in agriculture in recent years. It is used in agriculture to precisely arrange various operations and objectives while harnessing limited resources with minimal human intervention. Modern intelligent technologies and control systems simplify sensor data collection, making it more efficient than manual data collection, which can be slow and prone to errors. Specific ambient variables like temperature, humidity, light intensity, stock solution concentrations (nutrient water), EC (electrical conductivity), pH values, CO2 content, and atomization parameters (frequency and interval) are collected more effectively through these systems. The use of intelligent technologies provides complete control over the system. When combined with IoT, it aids in boosting crop quality and yield while also lowering production costs and providing data directly to tablets and smartphones in aeroponic propagation systems. It can potentially increase the system’s productivity and usefulness compared to the older manual monitoring and operating methods.

Adaptive Neuro-Fuzzy Interference System (ANFIS) Control of a Dynamic, Two-Region Nuclear Power Plant Pressurizer Model

Abstract Designing modern control systems is a critical factor in producing rigid control and effective performance of non-linear and complex systems—particularly employing intelligence-based controllers, derived from soft computing algorithms. It is known to be well capable of exploiting tolerances for uncertainty and nonlinearity. Fuzzy logic, which utilizes soft computing techniques, deals with vague information and approximate reasoning, yet it lacks effective learning capability, while ANN is known for exceptional learning and adaptation of training data. Adaptive neuro-fuzzy interference system (ANFIS), a hybrid of these two algorithms, is a fuzzy interference system optimized by neural networks. Most nuclear generating stations still use PID controllers, which does not show good controlling capabilities, resulting in large coolant level overshoot and longer settling time. This paper bridges this gap by testing an ANFIS approach that yields high predictive and control capability. In validating the configured control loop model, three loss-of-load transients from a Shippingport reactor were tested, trained and demonstrated using the simulations in the MATLAB/Simulink environment. The minimal training RMSE for the 51 MW(e), 74 MW(e), and 105 MW(e) loss-of-load transients are 18.85%, 19.37%, and 24.36%. The pressure response showed ideal output, with all three steady-state pressures close at setpoint (14 MPa), proving that the ANFIS controller is well capable of rejecting disturbances with lesser overshoot and faster settling times in maintaining level setpoint. Validating solely the pressurizer model was executed in a turbine leading power trip from a 100% to 75% reduction range in PCTRAN, a pressurized water reactor (PWR) simulator made available by IAEA. The comparative performance exhibited a good fit between the reported simulation data and model data. Both results against simulation and experimental transients captured the effective predictive and control capabilities of the pressurizer unit and control system.

Mathematical modelling of induction motors taking into account design-parameter asymmetry

Due to their numerous technical and economic advantages, induction machines (IM) with squirrel-cage rotors are important components of many industrial processes. Their reliability, durability, and ease of operation make them indispensable in various industries, ensuring stable and efficient equipment performance. However, to minimise the risk of costly production failures caused by sudden stoppages, it is important to implement effective diagnostic and monitoring methods. The most common type of fault in squirrel-cage induction motors is the breakage of cage bars and end ring segments, particularly in motors with high inertia loads and frequent stops and starts. Regular maintenance and the implementation of modern control systems in the industry will help ensure the reliable and uninterrupted operation of these machines. In the technical literature, various diagnostic methods have been proposed. Some are based on analysing data collected from the induction motor (IM), detecting characteristic perturbations that indicate faults in the machine. Other methods involve comparing the data obtained from the actual induction motor with its digital model. It is clear that accurate and adequate IM models are necessary for the development and optimisation of fault diagnosis methods. This paper focuses on developing a mathematical model of an induction motor (IM) in a stator-fixed coordinate system, where the squirrel-cage rotor of the IM is represented as a multiphase, symmetrically distributed winding system in space. The adequacy of the obtained model is demonstrated. The developed model allows for the analysis of various types of asymmetries in both stator and rotor of squirrel-cage induction motors

Разработка программного обеспечения для цифровых интерфейсов электромеханического датчика положения

For an electromechanical position sensor to be used in modern motion control systems, it must have technical means to transmit measurement results. It is also necessary to connect the sensor with equipment to configure and test it. In addition, the exchange of information between its elements that calculate, and generate and process signals may be required. To perform the listed functions of information interaction digital interfaces are designed. The choice of interface types depends on their purpose, and the algorithms of their use are implemented using software. The development of such digital interfaces for the controller of a sine-cosine rotary transformer in amplitude mode is an urgent task of modern motion control systems. When developing software for digital interfaces, methods of algorithmization of control and information transfer processes, methods of software development and debugging, as well as experimental research methods have been used. Information interaction between the controller of the electromechanical position sensor and the high-level controller as part of the motion control system and ensuring its operability is carried out using various digital interfaces. The I2C interface is used to communicate the sensor with the high-level controller, and the UART interface is used to communicate with the equipment for configuring and testing. The connection between the generator and signal processor chip and the microcontroller included in the sensor is carried out via the I2C interface. The authors have developed a microcontroller driver for connecting to the I2C network bus in Slave mode, as well as a software handler for the UART interface, which detects received messages of a given format and ensure safe operation in case of receiving corrupted messages. To store the configuration parameters of the sensor, one can access to flash memory of microcontroller. As a result of the use of digital interfaces and algorithms of their implementation that carry out information interaction, the developed controller of electromechanical position sensor becomes a full-fledged element of motion control systems. The use of modern design tools and specialized function libraries based on high-level C language, helps to develop software that implements these algorithms for various interfaces.

State of the Art and Future Trends in Monitoring for Industrial Induction Heating Applications

Induction surface hardening (ISH) processes are widely used in the heat treatment of numerous industrial components, especially in the automotive industry. Since this industry operates under very demanding quality standards, it is crucial for these heat treatment processes to meet rigorous specifications to ensure the safety and reliability of the produced components. This implies the precise and repeatable control of certain parameters throughout the manufacturing process of each of the parts treated, through precise and reliable instrumentation in electromagnetically harsh environments. The main objective of this work is to define the monitoring process for an industrial IHS application, determining the control needs and the methods of measurement, recording, and verification of the parameters that ensure the quality of the process. This paper describes the monitoring process of induction surface hardening, emphasizing the use of sensors and modern measurement and control systems. A comprehensive monitoring system supported by a programmable logic controller (PLC) and mixed acquisition and instrumentation systems (analog and digital) implemented with a high-performance Field Programmable Gate Array (FPGA) will be presented.

『기생 및 창기에 관한 서류철』의 원(原)자료 재구성에 관한 연구: 대한제국 말기 ‘전문 예술인 기생’에 대한 일제 통감부의 정책과 그 변화과정

This study targeted a total of 58 pages of Gisaeng-related documents, including all Gisaeng -related documents for [Records of Gisaeng and Prostitute] and 3 pages of [Agenda on Gisaeng and Prostitute Regulation Enforcement Instructions] that did not exist in the original copies and were newly discovered during the preliminary research. Then, this study examined each document and reorganized them based on the time sequence of documentation for a precise and detailed clarification on the details and process of changes in the policies that the Resident-General enforced on the Gisaeng, who was a professional performer during the late Korean Empire. First, [Gisaeng Regulation Law] began the modern Gisaeng system from September 25, 1908. The Resident-General first set to investigate and identify the personal information of the official Gisaengand transfer them to the Metropolitan Police Department. Second, the Resident-General enacted and confirmed the [Gisaeng Regulation Law] on September 15, 1908. As the internal official, Byungjun Son, approved the law on September 24, 1908, the [Gisaeng Regulation Law] was enforced on September 25, 1908, as the beginning of the modern Gisaeng system. Third, the Resident-General established a legal and political system for modernized control and management of Gisaengs (including official Gisaeng) who were working under the existing traditional Gisaeng system by enacting the series of Gisaeng-related laws and regulations, including [Gisaeng Regulation Law], [Standard Regulation of Gisaeng Association], [Proclamation on Gisaeng] in September 1908. Fourth, the Resident-General enacted the [Notice on Gisaeng and Prostitute Regulation Law Enforcement] and its detailed guidelines, [Detailed Notice on Gisaeng and Prostitute Regulation Law Enforcement] in October 1908, as the guidelines to be aware and conducted by the Japanese police officers of each local police station and each police station branch. The Resident-General also arranged and confirmed the formats for reporting operation, closure, address change, etc., of Gisaeng and prostitutes. Lastly, Gisaengs who were travelling for local tour, overseas tour, or other performances were required by the Resident-general to submit detailed contracts, contract details, and petition with names and addresses of Gisaeng and all performers. These documents were used to establish a modern management and control system for determining the authorization. This Gisaeng management and control system organized by the Resident-General during the late Korean Empire developed more systematically by the beginning of the Japanese colonial rule.

Control program for the dosing system of dry bulk feed components

The development of intensive farming technologies is impossible without the introduction of modern technologies. The problem of compound feed production in the voiced aspect can be solved not only through the development of new machines and equipment, but also the introduction of modern control systems. The article presents an analysis of existing dispenser control systems. Based on the analysis of programs and control systems, it was revealed that almost all programs are designed to work in limited conditions, some of them do not take into account a number of factors affecting the accuracy of the material supply. Therefore, a control program for a twin-screw dispenser is proposed. When developing the management program, we started from the technological process of dosing. The possibility of controlling two augers was taken into account: first, a large auger (driven by an asynchronous electric motor) turns on and feeds the main part, then it turns off and the second small auger (driven by an asynchronous or stepper motor) turns on, which carries out the filling of the remaining part. In this case, signals about the amount of material supplied are transmitted from weighing sensors (strain gauges). The proposed control program for the twin-screw dispenser is developed for the TM241C24R PLC in the Structured Text (ST) programming language, one of the languages of the IEC61131-3 standard, in the EcoStruxure Machine Expert programming environment. The control is displayed on a liquid crystal display. The main screen displays basic information: the parameters of the electric motor, the recipe and the readings of the weighing sensors. The program allows you to control the operation of dispensers in several modes. In automatic mode, each dispenser supplies only one component. In manual control mode, the dispensers are started and stopped by the operator from the control panel. In this case, it is possible to set the rotation speed of the dispenser shaft. In the dosing mode with two augers, one component is dispensed with two augers. The proposed program will improve the accuracy of dosing in automatic mode.

Current and future trends in vertical transportation

In the middle of the 19th century, the invention of a safety device that prevented elevators from falling enabled the construction of tall buildings and skyscrapers. In the middle of the 20th century, control systems started to serve the given calls automatically by relay technology, and later by electro-mechanical systems. In the 1970s-80 s, software-based control systems invaded elevator technology. Passenger service levels improved with the application of mathematical methods such as artificial intelligence. When the old relay boards of the skyscrapers in New York were modernized by software-based group controls, passenger waiting times dropped to less than half. In this millennium, the need to reduce elevator core space has further increased, since a significant number of buildings already exceed 300 m. The challenge in constructing tall buildings is that elevator groups can occupy the rentable area of a building. At the elevator planning stage, elevator core space can be decreased by zoning the building. The latest trends include systems with several elevator cars running in the same shaft. With modern control systems, passenger journey times can be decreased and handling capacity increased. This article deals with mathematical methods used in elevator dispatching problems. Building traffic simulation is utilized to search for an elevator arrangement that saves the most space in an example building. The design criteria of the ISO 8100–32 standard are used in selecting the elevator arrangements.

Study of operating modes of the AION tanker electrical power system

THE PURPOSE. Consider the issue of automation of modern sea vessels with a high degree of electrification. The purpose of the study is to analyze the electrical power system of the AION tanker to determine the possible occurrence of abnormal phenomena during parallel operation of generator sets and methods for eliminating them. METHODS. The article analyzes the electrical power system and automatic control devices of the AION tanker. Particular attention is paid to the study of systems that ensure the production and distribution of electrical energy between consumers. The widespread use of modern computer-based automatic control systems in ship power plants has been noted. The extensive possibilities for controlling a ship's electrical power plant in various daily or emergency situations are shown. The software and hardware of the ship's Power Management System allows you to reduce the consumption of fuel, oil and other important resources by automatically regulating the load on diesel generators, timing the supply of fuel to the cylinders, and controlling exhaust and starting valves. RESULTS. Experimental oscillograms of studies of the parallel operation of diesel generator sets were obtained, in which power exchange oscillations were recorded. The amplitude of power exchange oscillations reaches 40 % of the steady-state value, and their period is 600 - 800 ms, depending on the operating mode of the ship's electrical power system. During thecollection of these oscillograms, the ship's load is turned on and no starts or stops of any powerful consumers are made, that is, a quasi-steady process takes place. CONCLUSION. It is proposed to introduce a function for eliminating power exchange oscillations into the ship power plant control system. To implement it, it is necessary to add a block that receives information from all parallel operating diesel generator sets and adaptively adjusts the settings of the frequency regulators.

From PID to ADRC and back: Expressing error‐based active disturbance rejection control schemes as standard industrial 1DOF and 2DOF controllers

AbstractIn this paper, we uncover a new connection between standard proportional‐integral (PI), proportional‐integral‐derivative (PID) controllers and active disturbance rejection control (ADRC), from which we establish formal conditions of equivalence between the two control schemes. Using the equivalence, we devise a step‐by‐step procedure of transitioning from PI/PID to error‐based ADRC. We also show how to go from one degree‐of‐freedom (1DOF) to two degree‐of‐freedom (2DOF) ADRC while retaining a standard 2DOF PI/PID structure. Both procedures facilitate expressing error‐based ADRC schemes as standard industrial 1DOF and 2DOF controllers. This allows the designed controller to have the desired characteristic of ADRC (i.e., strong robustness against internal and external uncertainties) while still being expressed in a form that is familiar to industrial practitioners, where PI/PID structures are still the workhorse of modern control systems. The paper's results ensure backward compatibility of future ADRC‐based solutions and foster the adoption of active disturbance rejection‐based methods in industrial practice as a viable alternative to standard controllers. To further support the findings, a set of tests is conducted in time and frequency domain.

Система автономного управления дорожно-строительной машиной

The increasing requirements for the accuracy of construction work lead to the need to create modern control systems that will eliminate the human operator from the process of controlling road construction machines, increase the energy efficiency and productivity of these machines, as well as the quality of the finished construction object. The use of unmanned control systems has become an absolute technological break-through. Improving the accuracy of work with the help of unmanned control systems is an urgent and complex area of research. This is due to the need to improve algorithms and improve sensors to more accurately de-termine the coordinates of the machine and make decisions. Only by possessing high accuracy, modern unmanned vehicles are able to minimize errors in construction work and associated safety risks. To do this, it is necessary to provide the ability to recognize and analyze various factors, such as moving objects, weather conditions, terrain, etc. The article presents the results of a functional analysis of a number of road construction machines, defines the range of tasks that a modern unmanned control system should solve, describes a possible implementation option for such a system, and shows the differences in flowcharts of working processes of construction machines both without automatic control systems and equipped with standard and developed automatic control systems.

Epidemics, disease control, and China’s long-term development

This study examines the impact of historical disease burden on the development of contemporary China. Using historical records spanning nearly six centuries, we construct a county-level dataset for the distribution of epidemics in China. Our results indicate that historical disease pressure has a positive impact on long-term economic development. This positive association withstands rigorous testing through a series of robustness checks. Furthermore, we find that earlier institutional development in disease control and the improvement in human capital are effective channels. The establishment of disease prevention centers facilitated the early adoption of modern disease control systems, which, in turn, enhanced public health, education, and productive activities.

On the Global Stability of Nonlinear Hurwitz Control Systems

The problem of designing nonlinear control systems by the algebraic polynomial-matrix method using quasilinear models is considered. The quasilinear models of nonlinear plants are easily created on the basis of their nonlinear equations in the Cauchy form. To create these models only the differentiability of the plants nonlinearities is required. The solution to the design problem of the nonlinear Hurwitz control systems using the algebraic polynomial-matrix method is available if the quasilinear model of the plant is controllable. The design with application of this method consists of creating the quasilinear model of the nonlinear plant, generating several polynomials, composing and solving a system of linear algebraic equations. The theorem about the global stability of the equilibrium of the nonlinear systems, represented in the quasilinear model, is proved by the method of Lyapunov functions. The numerical examples of the design of nonlinear Hurwitz control systems are given. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Note to Practitioners</i> —This article is concerned with the creation of stable nonlinear control systems with nonlinear elements since the linear systems can’t fulfill the quality requirements demanded from modern control systems. Additionally, the known design methods of nonlinear systems, such as the input-state feedback linearization, backstepping, passivity and others, require the transformation of the original nonlinear equations of the plant into some special form. These transformations are often very difficult to find and to execute. A new algebraic polynomial-matrix design method of the nonlinear control systems using the quasilinear models of nonlinear plants is proposed in the article. This method can be applied if the nonlinearities of the plant are differentiable, and the quasilinear model of the plant is controllable. The theorem about global stability of the equilibrium is proved for the systems designed with this approach. The quasilinear models are easily created on the basis of the original equations in the Cauchy form for a given nonlinear plant. The algebraic polynomial-matrix design method is very simple: the quasilinear model is created; several polynomials are calculated with the use of this model and the linear algebraic equations system is composed. The solution of this system allows us to write down the expression which defines the control law as a nonlinear function of the plant’s state variables. This system will be globally or locally stable if the conditions of the theorem or the corollaries, proved in this article, are satisfied. The numerical examples illustrate the application of the suggested approach to the design of nonlinear Hurwitz control systems for the nonlinear plants. The main advantages of this approach: the quasilinear models are created quite easily; the nonlinear control law is found as a solution to the system of linear equations. The results can be applied to the creation of nonlinear control systems of nonlinear plants in many industries: shipbuilding, aircraft construction, automobile construction, agriculture and many others.
