Simulation of an Asynchronous Motor

Performing asynchronous motor simulations in the MATLAB/Simulink environment enables comprehensive simulation results, forming the fundamental basis for direct torque control (DTC) systems. The simulation allows you to observe the motor's operational characteristics and differences compared to other motor types. Through parameter adjustment in Simulink blocks such as the Asynchronous Machine block and control subsystem components, users can modify electrical parameters (stator resistance, rotor resistance, mutual inductance) and mechanical parameters (inertia, friction) to analyze different performance outcomes. This parameter tuning capability helps better understand motor performance under various operating conditions. In practical applications, comprehending motor performance and operational behavior is crucial for proper motor selection and control strategy development. The simulation implements key algorithms including flux and torque estimation using voltage and current measurements, hysteresis band control for torque regulation, and switching table-based inverter control. Therefore, conducting asynchronous motor simulations represents an essential step in learning and understanding motor control principles, providing hands-on experience with DTC algorithm implementation through Simulink's graphical programming interface and signal analysis tools.
