SIMULINK Simulation of Permanent Magnet Synchronous Motor Vector Control System

In this article, I will demonstrate how to perform simulations of permanent magnet synchronous motor (PMSM) vector control systems using MATLAB/SIMULINK. This simulation approach helps users deeply understand the working principles and performance characteristics of PMSM control systems. The implementation typically involves key components such as Clarke/Park transformations for coordinate conversion, space vector pulse width modulation (SVPWM) techniques, and PI controllers for current and speed regulation loops. I will also share practical implementation techniques and experiences, including parameter tuning methods for controllers and modeling considerations for inverter components, to help users effectively handle various scenarios in real-world applications. The article aims to provide valuable assistance while inspiring further interest and research enthusiasm in motor control technologies, with specific focus on MATLAB function blocks like PMSM machine models, dq-axis current controllers, and speed estimation algorithms.
