摘要：基于电压空间矢量调制的永磁同步电机调速控制模式，提出一种改善调速系统精度的重复控制方法。重复控制可使系统稳态运行无静差，将重复控制嵌入到矢量控制模式下的调速系统中，系统精度得到显著提高。仿真结果表明，采用重复控制策略，系统响应速度快、抗干扰性能好、稳态运行精度高，获得较好的动静态性能。

Abstract: Repetitive control was proposed to improve the speed accuracy of permanent magnet synchronous motor（PMSM） based on space vector pulse width modulation (SVPWM). The system has no steady-state error with implementation of repetitive controller. The simulation results show that the system can achieve high-dynamic response, anti-jamming performances and near perfect speed. The dynamic and static performance of the control system is improved greatly.
