Simulation Model of Permanent Magnet Synchronous Motor Direct Torque Control System

This paper presents a comprehensive simulation model of the direct torque control (DTC) system for permanent magnet synchronous motors (PMSM), exploring various aspects of the model implementation. The discussion begins with the model design process, including system modeling using mathematical equations and parameter adjustment methodologies. We then provide detailed explanations of the control algorithms and strategies employed during simulation, such as hysteresis band comparators and switching table implementations, along with their advantages and limitations in practical applications. Furthermore, the paper examines methods for analyzing and evaluating model performance through torque and flux linkage response characteristics. Optimization techniques for enhancing model performance, including improved switching strategies and advanced control algorithms, are also introduced. Finally, we share practical challenges encountered during model simulation, along with corresponding solutions involving MATLAB/Simulink debugging and parameter tuning, while discussing future research directions and potential application prospects in industrial drive systems.
