摘　　要：应用SVPWM的基本原理,在MATLAB平台上搭建永磁同步电动机(PMSM)矢量控制系统模型。为了改善传统PI调节系统的动态性能,引入一种智能PI调节器作为转速控制器。仿真结果得出:同样的仿真环境下,应用智能PI调节器的控制系统的起动定子电流、起动电磁转矩、动态速降和恢复时间均小于使用传统PI调节器的控制系统,为提升PMSM控制系统的整体性能提供新思路。In this paper,by using the SVPWM,a PMSM control model was built in the MATLAB/Simulink platform.A intelligent PI controller was adopted as speed controller to improve the dynamic performance by using conventional regular system.Simulation results show that：under the same simulation development,startup stator current,startup electromagnetic torque,dynamic speed change and recovery time of proposed intelligent PI regulator system are less than that of conventional PI regulator system.It offers a new strategy for improving the overall performance of PMSM control system.
