Implementation of PMSM Simulation Based on SVPWM Technique

A MATLAB/Simulink-based simulation has been implemented for Permanent Magnet Synchronous Motor (PMSM) utilizing Space Vector Pulse Width Modulation (SVPWM) technique, achieved through reference voltage-oriented simulation approach.

This simulation employs MATLAB/Simulink software tools to model and analyze the operational characteristics of SVPWM-driven PMSM systems. The implementation involves creating functional blocks for SVPWM signal generation, PWM inverter control, and motor dynamic modeling. Key components include Clarke/Park transformations for coordinate conversion, voltage vector sector identification algorithms, and duty cycle calculation modules for precise gate signal generation.

By inputting reference voltage signals into the simulation environment, we can observe and analyze PMSM behavioral patterns and performance metrics such as torque ripple, speed response, and current harmonics. The simulation architecture incorporates PID controllers for speed regulation and current control loops, with real-time monitoring capabilities for waveform analysis. This methodological approach facilitates comprehensive understanding and optimization of PMSM system operations, enabling performance validation before hardware implementation.
