摘　　要：本文简述纯电动汽车驱动电机系统控制原理,并针对某纯电动汽车在连续颠簸路面驱动电机系统过流故障进行分析,基于永磁同步电机矢量控制的电压前馈补偿型电流调节器,提出了优化转速滤波的方案,通过实际路况验证,有效解决了连续颠簸路面驱动电机系统过流故障。This paper describes the common control principles of the drive motor system in a pure electric vehicle,and analyzes the over-current fault of the drive motor system in a pure electric vehicle on the continuous bumpy road.A scheme of optimizing speed filter based on the voltage feedforward compensating current regulator in PMSM vector control is proposed,and verified by actual road conditions.It has effectively solved the over-current fault of the driving motor system on the continuous bumpy road.
