Purpose. Development of a laboratory stand with a wireless interface for the study and research of automatic control systems for DC electric drives. Methodology. Physical experiment on the developed laboratory bench, computer modelling, calculation and analytical methods. Findings. The study considered and analyzed the advantages and disadvantages of existing developments of laboratory stands with virtual and remote components, the possibility of organizing a wireless interface, taking into account cost-effectiveness, mobility, reliability and simplicity, as well as the possibility of using as a training stand. The connection of the stand by means of USB and Wi-Fi is developed. The STM32F103C8T6 microcontroller is used for the power switch and the automatic control system. The interface part consists of a NodeMCU board, a MicroSD card module, an interface control unit, a 16x2 LCD and an I2C converter. The UART-USB interface is used for information transfer and programming of the stand. The possibility of current remote transmission of information about the modes and parameters of the engine to a computer with a browser output by installing the Wi-Fi module ESP8266MOD. A closed system of automatic DC motor control with PID current regulators and EMF has been developed. Experiments were performed with a pulse and smooth increase in motor speed and variation of the components of the PID controllers using the control panel of the laboratory stand. All graphs of the results of the experiment were obtained on a web page with a fixed IP address in the browser via Wi-Fi. Originality. The structure of the remote monitoring and control system based on hardware and software combination of telecommunication and measuring systems is proposed and developed, which differs from the existing ones by the presence of current wireless transmission of information, which allows to remotely receive research data of automatic DC motor control systems. Practical value. The developed laboratory stand with the wireless interface allows to receive and store experimental data on parameters of the investigated engine in real time remotely.

“…Ever increasing interest paid to applications of fractional calculus has necessitated development and study of special numerical methods for solving fractional-order differential equations (FDE). Finding analytical solutions for FDE is indeed more difficult than solving ordinary differential equations (ODE) and it is possible to provide numerical approximation of solution in most cases [18,19]. Numerical methods for solving FDE problems are widely studied.…”

“…For such systems, in most practical cases, with the help of typical PID controllers, it is not possible to fulfill the technical requirements for the system, which necessitates the use of more complex controllers and modern methods of their synthesis [10][11][12]. One of the main requirements for multi-mass control systems is also the requirement for the robustness of the synthesized system, i.e.…”

Aim. Development of the method of multi objective synthesis of nonlinear robust control by multimass electromechanical systems to satisfy various requirements for the operation of multi-mass systems in various modes. Methodology. The problem of multi objective synthesis of nonlinear robust control of multimass electromechanical systems is formulated and the possibility of satisfying various requirements for the operation of such systems in various modes based on the concept of functionally multiple membership of the state vector and the solution of the Hamilton-Jacobi-Isaacs equation is shown. A method for choosing weight matrices with the help the vector of purpose of nonlinear robust control is formed by solving a zero-sum vector antagonistic game has been substantiated and developed. Results. The results multi objective synthesis of nonlinear robust two-mass electromechanical servo systems in which differences requirements for the operation of such systems in various modes were satisfied are given. Based on the results of modeling and experimental studies it is established, that with the help of synthesized robust nonlinear controllers, it is possible to improve of quality indicators of two-mass electromechanical servo system in comparison with the system with standard regulators.
