Improving the Step Response of Flexible Systems in the Presence of Real Nonminimum Phase Zeros

Abstract It is well known that real nonminimum phase (RNMP) zeros impose a tradeoff between the settling time and undershoot in the step response of flexible systems. Existing methods to alleviate this tradeoff predominantly rely on various advanced control strategies without delving into a broader mechatronic approach that combines physical system and control system design. To address this gap, this article proposes a proportional viscous damping-based physical system design in combination with feedback control and prefilter design. First, the effect of proportional viscous damping on RNMP zeros of flexible systems is established to propose a damping strategy that pushes all the RNMP zeros further away from the imaginary axis. Then, a step-by-step mechatronic system design process is presented to apply this damping strategy along with a full-state feedback control strategy and prefilter to a multi-degree-of-freedom (DoF) flexible system. The application of this design process yields simultaneous improvement in the settling time and undershoot in the step response of this flexible system.

УПРАВЛЕНИЕ ПЛАВАНИЕМ КОМПОЗИТНОГО ЭЛЕКТРОМЕХАНИЧЕСКОГО МИКРОРОБОТА

Relevance Currently, underwater robotics is one of the most important areas of development of robotic complexes. Their foundation and control are based on an electromechanical basis. The creation and research of electromechanical systems are one of the promising areas of development of electromechanics and electrical engineering. Equipped with a wide range of sensors, unmanned underwater vehicles are widely used to solve tasks such as studying the seabed relief, monitoring and servicing oil and gas pipelines and cable lines, collecting biological and geological samples of liquids, developing offshore oil and gas fields, conducting underwater rescue operations. The increasing popularity of such devices is explained by the fact that the use of manned vehicles can be very dangerous for the life of the pilots themselves and incur high costs during their operation. Research conducted by various engineering groups in the field of modeling and control of underwater robots is ultimately aimed at achieving full automation of processes. Achieving this aim seems to be an extremely difficult task, since it requires knowledge and understanding of a large volume of theoretical and practical problems that are subject to comprehensive research. Aim of research To carry out theoretical calculations on the study of electromechanical and mechanical parameters of underwater robot control and compare them with experimental data. Research methods The theory of electromechanical energy conversion and control of electrical equipment, methods of mathematical and physical modeling were used in the work. Results The results of constructing an algorithm and a mathematical model of the device of an electromechanical composite robot are presented. A system of equations of mechanics and electrodynamics was used to describe its power characteristics. By solving this system of equations, a theoretical analysis of the operation of its engine was carried out. With the help of the mechatronic approach, its swimming and coordination of its functional modules are studied. The results of this article will be useful for engineers involved in the design and operation of robots using robotic systems in the fields of biotechnology and biomechanics.

Load Cell Mechatronic Approach with Finite Element Analysis (FEA) in SolidWorks Design Development of a Small-Scale Egg Sorter

This research was about developing an automated small-scale egg sorting machine, equipped with mechatronic components, that can sort chicken eggs and place them in trays according to five (5) weight classifications: pewee, small, medium, large, and extra-large with the use of an Arduino load sensor. The machine was made up of a load cell sensor, an Arduino mega controller, a suction mechanism hanging from a rail system driven by a National Electrical Manufacturers Association (NEMA) stepper motor, and a set of five egg trays for the five (5) egg weight classifications. The Arduino Mega microcontroller was used to operate the machine's moving parts, pump, sensors, and LCD. The machine was equipped with an alarm system that produces a sound when the suction picks up the 13th egg of a full tray. The Finite Element Analysis (FEA) simulation was done using SolidWorks software to analyze the vacuum pump capacity and the effects of dynamic force on the eggs during the pick and place process. Testing results of the actual fabricated machine indicated that it was able to successfully weigh, pick through suction, sort, and place eggs into 2x6 trays according to weights. The accuracy was 92.55 percent.

A framework for development of digital twin industrial robot production lines based on a mechatronics approach

During the past years, intelligent manufacturing has attracted enormous attention from both academia and industry. Smart factories/workshops/production lines are important carriers for realizing intelligent manufacturing. However, there are difficulties in smart factories in processing multi-source heterogeneous data, in integrating virtual and physical worlds, and in achieving continuous and iterative optimization with real-time feedback. Digital twin, which is able to deeply integrate physical and virtual worlds, provides an important technology for easing the difficulties mentioned above. The construction of a digital twin system can solve the problem of data fusion, analysis, processing, and applications in smart factory. Digital production lines are the foothold of a smart factory. Building a digital twin production line can facilitate rapid practice of digital twins and promote the development of intelligent manufacturing. To this end, this paper proposes a development framework for a digital twin production line with closed-loop control based on a mechatronics approach. The detailed development process is given based on the framework. The framework proposed may provide some inspiration and insights for design and development of digital twin production lines.

The Delta Robot-A long travel nano-positioning stage for scanning x-ray microscopy.

A new stage design concept, the Delta Robot, is presented, which is a parallel kinematic design for scanning x-ray microscopy applications. The stage employs three orthogonal voice coils, which actuate parallelogram flexures. The design has a 3 mm travel range and achieves rms position jitter, integrated from 1 Hz to 1 kHz, of 2.8 and 1.3 nm perpendicular to the beam and 5.6 nm along the beam direction with loads up to 350 g. The Delta Robot design process used a mechatronics approach of iterative modeling and simulation to develop the system and validate performance.

Range-Extended Confocal Chromatic Sensor System for Double-Sided Measurement of Optical Components With High Lateral Resolution

This paper presents a strategy to break the tradeoff between the thickness measuring range of a confocal chromatic sensor (CCS) and its lateral imaging resolution. By combining the sensor with a linear stage, the thickness measuring range is no longer limited by chromatic dispersion, but by the focusing power of the sensor optics. The principle is demonstrated with a prototype setup that utilizes a CCS with a spot size of 6 μm and a spec-sheet thickness measuring range of 300 μm. By implementing the proposed mechatronic approach, a successful extension of the measuring range by a factor of 17 is achieved while preserving the lateral resolution of 2.46 μm for thickness measurements. The proposed measurement scheme is validated by measuring lateral surface features on a 1.2mm thick lenslet array from the backside.

Safety Control Architecture for Ventricular Assist Devices

In patients with severe heart disease, the implantation of a ventricular assist device (VAD) may be necessary, especially in patients with an indication for heart transplantation. For this, the Institute Dante Pazzanese of Cardiology (IDPC) has developed an implantable centrifugal blood pump that will be able to help a diseased human heart to maintain physiological blood flow and pressure. This device will be used as a totally or partially implantable VAD. Therefore, performance assurance and correct specification of the VAD are important factors in achieving a safe interaction between the device and the patient’s behavior or condition. Even with reliable devices, some failures may occur if the pumping control does not keep up with changes in the patient’s behavior or condition. If the VAD control system has no fault tolerance and no system dynamic adaptation that occurs according to changes in the patient’s cardiovascular system, a number of limitations can be observed in the results and effectiveness of these devices, especially in patients with acute comorbidities. This work proposes the application of a mechatronic approach to this class of devices based on advanced control, instrumentation, and automation techniques to define a method to develop a hierarchical supervisory control system capable of dynamically, automatically, and safely VAD control. For this methodology, concepts based on Bayesian networks (BN) were used to diagnose the patient’s cardiovascular system conditions, Petri nets (PN) to generate the VAD control algorithm, and safety instrumented systems to ensure the safety of the VAD system.

Design Study of Multi-Rotor and Multi-Generator Wind Turbine with Lattice Tower—A Mechatronic Approach

New locations for onshore technology, which have not been considered so far, must be developed to increase the total installed capacity of renewable energies, especially wind energy. For this purpose, cost-effective wind turbines, even in difficult-to-access locations, such as mountainous and high-mountainous areas, must be designed. This paper presents a novel wind turbine with a related control system that meets these requirements. The proposed turbine uses a multi-rotor configuration with five rotors arranged in a star shape configuration. Each rotor drive train combines up to 12 generators in a maintenance-friendly multi-generator concept. A suitable observer-based control for load mitigation in the full-load region is proposed for the multi-rotor and multi-generator design. Simulations are used to demonstrate the applicability and practical benefits of this concept.

Synchronized switch piezoelectric energy harvesting using rotating magnetic ball and reed switches

Synchronized switch harvesting on inductor (SSHI) interface circuit has been developed to boost the harvesting capability of piezoelectric energy harvesters (PEHs). Although some electronic self-powered peak-detector and switching circuits have been proposed to support the practical realization of SSHI, the energy dissipation and voltage drops in transistors and diodes of the self-powered circuits might significantly deteriorate the actual energy harvesting performance. Some mechatronic designs were proposed as well. However, most of their switches are activated by touch impacts, which might introduce undesired high-order vibrations to the main structure. In this paper, rather than using the impact-engaged strategy discussed in the literature, a new mechanism using a magnetic ball for vibration synchronization and reed switches for switching operation is proposed. A PEH shunted to an SSHI interface circuit using the proposed mechatronic approach has been prototyped. Since the peak-detection and switching operations are completed by a mechanical mechanism, less passive electrical components, which consume extra energy, are required in our proposed design. Therefore, the overall energy harvesting performance is improved. Numerical simulations and experimental tests have validated the feasibility of the proposed design. The experimental results have shown that the power output produced by the proposed mechatronic self-powered SSHI design can be increased by and , as compared with the cases using a benchmark standard energy harvesting bridge rectifier and an electronic self-powered SSHI solutions, respectively. Moreover, owing to the new mechatronic design, the auxiliary mechanical components are embedded in the tip block of the cantilevered PEH, rendering the whole system to be a compact design.

The effect of various forming parameter such as, forming pressure, bulge forming time and thickness distribution of the sheet in a re- entrant shape product. Finite Element analysis is a powerful tool to evaluate the superplastic forming processes (SPF) with accurate prediction of the deformation characteristics.

Mechatronic approach in hydraulic braking system

In present automotive sector there are magnificent transformations from mechanical to electrical with intensive changes. Each and every one is showing enthusiasm towards vehicles. In addition, humans are very much fascinated towards vehicles where they are driving faster than before. Many types of braking system have been introduced but this paper explains whether the brakes can be applied with less human effort by removing the solid linkage present in between pedal and master cylinder. In order to make the braking system economical and affordable, we are introducing a mechatronic technique which helps us in eliminating the solid linkage present in between the pedal which is linked to master cylinder, linking the pedal to linear potentiometer for the resistance. As the resistance starts varying, difference in braking will be observed. This technique helps in reducing manual effort. Working will be effective and efficient if the components are given more than recommended power supply.

Energy Current Analysis of an Improved Self-Adaptive Mechatronic Approach for P-SSHI

The approach of mechatronic switch appears to be a promising way of elaborating self-started synchronous switching circuits for piezoelectric energy harvesting. In order to replace electronic switches, the mechatronic switch has to overcome a critical challenge: how to trace the variable amplitude adaptively in different vibration situations while bringing less damping to the system dynamics as possible? In this article, an improved design of self-adaptive mechatronic switch is proposed by using the snubber structure of viscous materials in series with a low-frequency oscillator. The duplicated effects of the oscillator's slow responses and the relaxation process of the viscous materials bring the advantages of reducing switching phase mismatch and enhancing the performance with less parameter sensitivity. In addressing the damping doubts, energy current analysis is performed for different parameters. It reveals that the mechanical loss from the mechatronic switch can be controlled to a faint level. Superior performance of the proposed approach is confirmed in comparison with the standard circuit for weakly coupled cases.
