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。

Abstract:The basic principle of the permanent 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 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
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 side converter can be improved.
