Comparative Study of Permanent Magnet Synchronous Motor Control System Based on Rotor Field Oriented Control

介绍了基于转子磁场定向的永磁同步电动机(PMSM)矢量控制系统的原理,依据Clark变换、Park变换、空间矢量调制(SVPWM)和磁场定向控制等理论,借助Matlab/Simulink搭建了PMSM矢量控制仿真系统,研究了比例-积分-微分(PID)、积分分离式PID和比例-积分(PI)3种控制方式下PMSM矢量控制系统的启动性能、抗干扰性能和调速性能。仿真结果表明:采用积分分离式PID控制方式较传统PID和PI控制方式的PMSM矢量控制系统具有更好的启动特性、动态响应、调速性能和转矩性能。

This paper introduces （PMSM） vector control system using the principle of permanent magnet synchronous motor field oriented control system based on rotor. According to the principle of Clarke and Park transformation, space vector pulse width modulation（SVPWM） , and the theory of field oriented control, the paper builds a control simulation system of PMSM with Matlab/Simulink. Starting anti-jamming and speed control performance of PMSM vector con- trol system are studied using three difference control styles. PID, integral separated PID, and PI. Simulation results show that a PMSM vector control system using integral separated PID has good startup characteristic, fast dynamic response, wide speed range and good torque performances as compared with PID and PI.
