Implementation of Induction Motor Speed and Torque Control System with Reduced Order Model in ANSYS Twin Builder

This paper deals in detail with the development of a vector Field Oriented Control (FOC) system for the modes of operation of an induction motor with a squirrel cage rotor using ANSYS Twin Builder. Despite the fact that the theory of vector control system is well known, and its implementation is fully disclosed in Matlab/Simulink, such task is new in the ANSYS Twin Builder software. The use of ANSYS Twin Builder attracts first of all the advantages of using an imitation model as a digital twin of a real technical object with two-way communication, in this case it is an induction motor. The paper shows the stages of creating a reduced-order model (ROM) of an induction motor, importing the ROM of the motor into Twin Builder, forming the structure of the vector FOC system for controlling the speed and torque of the induction motor in Twin Builder, configuring and connecting library modules based on standard and VHDL ones. Simulation is performed in two stages. At the first stage, a joint (coupling) calculation of an induction motor with a squirrel cage rotor in ANSYS Maxwell and an imitation model in ANSYS Twin Builder was implemented. The second stage uses the induction motor ROM integrated into the ANSYS Twin Builder sheet. The obtained calculation results were analyzed and compared, and further research results were formulated, which will be aimed at the development of a digital twin of an induction motor with a squirrel cage rotor based on ANSYS Twin Builder. The paper will be useful to PhD students, scientific researchers, engineers of design departments of industrial enterprises that are engaged in the development of electric motors and their control systems, and enterprises that use controlled electric motors and need to monitor their operating modes in real time.
