Speed Control Simulation of Permanent Magnet Synchronous Motor Using Direct Torque Control in Simulink

This Simulink-based speed control simulation for permanent magnet synchronous motors employs Direct Torque Control (DTC) methodology, where custom modules are implemented using S-functions to enhance simulation speed. S-functions allow direct coding of control algorithms in MATLAB/C language, enabling faster execution compared to standard Simulink blocks. The simulation facilitates research and optimization of motor control systems, improving motor performance and efficiency through precise torque and flux regulation. Key implementation aspects include hysteresis comparators for torque and flux control, switching table logic for inverter control, and speed PID regulators. By modifying simulation parameters, different control strategies can be explored with performance evaluation and comparison capabilities. This simulation approach significantly reduces experimental costs and time while increasing research efficiency. Therefore, using Simulink for permanent magnet synchronous motor speed control simulation with Direct Torque Control proves to be a feasible and effective methodology for motor control system development.
