РОЗРОБКА СИСТЕМИ КЕРУВАННЯ КРОКОВИМ ДВИГУНОМ НАВЧАЛЬНОЇ ТРАНСПОРТНОЇ ЛІНІЇ

Stepper motors have long been successfully used in a variety of industrial and special equipment. The advantage of stepper motors is that a high degree of motion control can be achieved. Stepper motors are controlled using microprocessor systems. However, in this case, the stepper motor is controlled by the program loaded into the microcontroller. There is often a need to dynamically change the operation parameters of the stepper motor - speed of rotation, direction and magnitude of the angle of rotation, etc. The work is devoted to the development of the stepper motor control system of the educational transport line, implemented at the Department of Automation of Production Processes of the Ukrainian State University of Science and Technology. The system allows you to dynamically change system parameters using either a personal computer (PC) by sending the appropriate commands to the system via the COM port, or by using a tablet by sending the appropriate commands to the system via Bluetooth. Such a system can be used both in the educational process to practice standard stepper motor control techniques and microcontroller programming skills, and in industrial systems that require high-precision mechanism position control.

An Artificial Neural Network for Solar Energy Prediction and Control Using Jaya-SMC

In recent years, researchers have focused on improving the efficiency of photovoltaic systems, as they have an extremely low efficiency compared to fossil fuels. An obvious issue associated with photovoltaic systems (PVS) is the interruption of power generation caused by changes in solar radiation and temperature. As a means of improving the energy efficiency performance of such a system, it is necessary to predict the meteorological conditions that affect PV modules. As part of the proposed research, artificial neural networks (ANNs) will be used for the purpose of predicting the PV system’s current and voltage by predicting the PV system’s operating temperature and radiation, as well as using JAYA-SMC hybrid control in the search for the MPP and duty cycle single-ended primary-inductor converter (SEPIC) that supplies a DC motor. Data sets of size 60538 were used to predict temperature and solar radiation. The data set had been collected from the Department of Systems Engineering and Automation at the Vitoria School of Engineering of the University of the Basque Country. Analyses and numerical simulations showed that the technique was highly effective. In combination with JAYA-SMC hybrid control, the proposed method enabled an accurate estimation of maximum power and robustness with reasonable generality and accuracy (regression (R) = 0.971, mean squared error (MSE) = 0.003). Consequently, this study provides support for energy monitoring and control.

Strategy for Knowledge Management Sustainability: A Lesson from The Industrial Automation Unit

Organizational knowledge is a combination of individual’s knowledge within the organization. Specialize individual knowledge is developed inside the organization. Therefore, it should belong to the organization and be stored in the organization. The Industrial Automation (IA) department implements simple knowledge management (KM) in the form of a web blog. However, the KM implementation becomes inconsistent. This inconsistency can lead to knowledge loss and knowledge gaps if there are individual changes within the organization. This study aims to analyze the condition of the IA department’s KM, analyze the factors that affect the sustainability of IA’s KM and formulate strategies for the sustainability of IA’s KM. The analysis of KM is carried out with the following factors: culture, training and development, reward, performance system, and technology. Supervisor’s order is still something that can help to build the knowledge-sharing habit. Employees do not get training regularly. Employees feel that they have not received good appreciation for the knowledge sharing and have not been included in the performance appraisal. Technology has been well adopted in KM. SEM-PLS analysis shows that training and development is a significant factor of KM sustainability. SEM-PLS result and content analysis construct managerial implication and KM sustainability strategies formula: develop a yearly training plan, establish problem-solving forum, and improving KMS implementation. Keywords: content analysis, knowledge management, SEM-PLS, sustainability, training

A Methodology for Flexible Implementation of Collaborative Robots in Smart Manufacturing Systems

Small-scale production is relying more and more on personalization and flexibility as an innovation key for success in response to market needs such as diversification of consumer preferences and/or greater regulatory pressure. This can be possible thanks to assembly lines dynamically adaptable to new production requirements, easily reconfigurable and reprogrammable to any change in the production line. In such new automated production lines, where traditional automation is not applicable, human and robot collaboration can be established, giving birth to a kind of industrial craftsmanship. The idea at the base of this work is to take advantage of collaborative robotics by using the robots as other generic industrial tools. To overcome the need of complex programming, identified in the literature as one of the main issues preventing cobot diffusion into industrial environments, the paper proposes an approach for simplifying the programming process while still maintaining high flexibility through a pyramidal parametrized approach exploiting cobot collaborative features. An Interactive Refinement Programming procedure is described and validated through a real test case performed as a pilot in the Building Automation department of ABB in Vittuone (Milan, Italy). The key novel ingredients in this approach are a first translation phase, carried out by engineers of production processes who convert the sequence of assembly operations into a preliminary code built as a sequence of robot operations, followed by an on-line correction carried out by non-expert users who can interact with the machine to define the input parameters to make the robotic code runnable. The users in this second step do not need any competence in programming robotic code. Moreover, from an economic point of view, a standardized way of assessing the convenience of the robotic investment is proposed. Both economic and technical results highlight improvements in comparison to the traditional automation approach, demonstrating the possibility to open new further opportunities for collaborative robots when small/medium batch sizes are involved.

Various methods of circular interpolation performance analysis

The paper discusses the possibilities and methodology of utilizing software, designed to be used with a double ball bar device to analyze CNC machine tool positioning performance, to analyze measurements measured by a different method. The Renishaw Ballbar system is a special tool designed to allow rapid and highly effective checks of positioning performance of any numerically controlled cartesian structure, such as a CNC machine tool, and at the same time allows monitoring its condition and to some extent predict its future development. The system uses sophisticated algorithms to decompose the overall measured inaccuracy of examined machine to values of individual errors and offers possible actions to remove such errors. The ability to push different measurements of circularity, such as measurement of circularity of machined surface on a coordinate measuring machine, would allow checking the presence of various errors without the necessity to measure with a double ball bar device. Therefore, the paper presents the custom software, that shows such possibilities, which was developed at the Department of Automation and Production Systems, Faculty of Mechanical Engineering, University of Zilina.

Assessment of Characterization Procedures for the Implementation of Anaerobic Digestion Model No.1

In this paper, comparison were made among the characterization processes, designed for influent characterization in Anaerobic Digestion Model No.1 (ADM1) to choose one of the best available. The two procedures chosen are elemental analysis and conversion of Activated sludge Model (ASM) output to ADM1 input variables (ASM2ADM interface) given by John B. Copp, 2003. The Matlab code for elemental analysis was developed to facilitate computation and a c-file of the ASM2ADM interface was provided by the department of Industrial Electrical Engineering and Automation, Lund University Sweden. Both of these methods have been used in the collection of wastewater data from various locations and the demand for chemical oxygen (COD) after separation compared to experimental results. In almost all cases total fractionated COD from ASM2ADM interface was approximately equal to experimental COD. While as fractionation by elemental analysis shows variation from experimental value. Linear curve fitting was done between experimental COD and fractionated COD to check their equivalency. The elemental analysis method has lower value of coefficient of determination (R2 = 0.5468) than ASM2ADM interface (R2 = 0.9453). Based on the model requirements, it was concluded that ASM2ADM interface is the best option for influent characterization. Apart from obtaining good correlation with experimental COD, it provides all input variables for implementation of ADM1. While elemental analysis provide fewer fractionation and hence assumption of other input variables is must leading to deviation from actual model features. Features of both methods are also discussed in the paper.
