摘　　要：分析了永磁同步电机(PMSM)矢量控制的基本原理以及双级矩阵变换器的调制策略,针对常规PI控制器适应范围的局限性,引入了一种非线性PI控制方法。该方法以提高PMSM调速性能为目的,根据误差的大小动态改变PI控制器参数。基于TMS320F28335和EP2C8T144C8N开发了一套双级矩阵变换器驱动PMSM矢量控制系统,通过实验实现了PMSM的高性能调速,改善了功率变换器网侧电能质量。The basic principle of the permanent magnet synchronous motor（PMSM）vector control and the modulation strategies of double matrix converter are analyzed,then a nonlinear PI control method is introduced in accordance with the limited subject range of PI controller,it can alter the parameters of PI controllers depending on the errors,then the performance of the PMSM speed regulation can be improved.In addition,a set of two-stage matrix converter which is based on TMS320F28335 and the EP2C8T144C8N chip is developed to fed PMSM with vector control method.The experiments are carried out on the system,the results prove that the high-performance speed regulation of PMSM can be realized,and the quality of electric power net side converter can be improved.
