永磁同步电机矢量控制系统仿真与建模研究

分析了永磁同步电机(PMSM)的数学模型,在此基础上提出了PMSM矢量控制系统仿真建模新方法,在matlab6.5/simlink环境下,建立了速度控制模块、坐标变换模块、SPWM控制模块,并与PMSM本体模块和电压逆变模块有机组合,建立了PMSM控制系统的速度和电流双环仿真模型。仿真实验结果表明该方法有效,也适用于验证其他控制算法,为实际PMSM控制系统的设计和调试提供了新的思路.

Modeling and Simulation of PMSM Vector Control System Based on Matlab6.5

In this paper,based on the mathematical model of the permanent-magnet sychronous-motor(PMSM),a new way of PMSM vector control system model has been taken on.In matlab6.5/simlink,the isolated functional blocks,such as speed controller block,vector controller block,coordinate transform block,SPWM block etc.has been modeled.There are some blocks such as PMSM block,voltage inverter block which are provided by matlab6.5/simlink.By the organic combination of these blocks,a double loop of control system,the speed loop and a current loop are established.The validity has been testified by the simulation results and other control strategies can be applied to the system to testify their rationality.This novel method offers a new thought way for PMSM control system designing and debugging in actual application.
