Synchronous Motor Closed-Loop Speed Regulation SIMULINK Simulation Model

The SIMULINK simulation model for synchronous motor closed-loop speed regulation has been thoroughly validated using MATLAB. This model accurately simulates the speed regulation process of synchronous motors through a well-designed control system architecture. The implementation incorporates PID controller blocks for precise speed tracking, with anti-windup protection and gain scheduling features. The model uses Clarke/Park transformations for dq-axis current control and includes space vector PWM modulation for inverter control. Motor parameters such as stator resistance, inductance, and flux linkage are configurable through MATLAB workspace variables. Through SIMULINK simulations, we can analyze dynamic characteristics including startup transients, load disturbance rejection, and speed reference tracking performance. The model employs rate limiters for smooth acceleration/deceleration profiles and includes comprehensive protection logic for overcurrent and overvoltage conditions. MATLAB validation was performed using script-based testing with multiple operating scenarios, ensuring model accuracy through comparative analysis with theoretical predictions. The simulation results demonstrate stable motor operation across specified speed ranges with optimized control parameters. This verified model provides valuable insights into closed-loop speed regulation techniques, featuring real-time monitoring scopes for critical signals like rotor speed, electromagnetic torque, and three-phase currents. The modular design allows easy modification of control strategies and facilitates advanced algorithm development for synchronous motor drives.
