MATLAB Simulation of Direct Torque Control Algorithm for Permanent Magnet Synchronous Motors

The simulation of Direct Torque Control algorithm for Permanent Magnet Synchronous Motors based on MATLAB Simulink represents a significant research effort in motor control systems. During implementation, we optimized the core algorithm components including torque and flux hysteresis comparators, voltage vector selection logic, and PWM generation modules to achieve exceptional simulation performance. The simulation results clearly demonstrate the algorithm's high efficiency and reliability through comprehensive torque response analysis, flux linkage tracking, and speed regulation characteristics. This project contributes substantially to the field of motor control by providing a verified control strategy implementation with detailed subsystem blocks for stator flux estimation, torque calculation, and switching table optimization. The simulation interface maintains a clean, organized structure with clearly labeled parameters for easy configuration of motor specifications, controller gains, and sampling periods. The modular design approach using masked subsystems and configurable blocks makes it particularly suitable for modifications, performance enhancements, and integration with other control strategies. Overall, this research provides valuable reference material for permanent magnet synchronous motor control applications and establishes a solid foundation for future research work in advanced motor control algorithms and real-time implementation studies.
