摘要
对双绕组永磁同步电动机控制策略进行了讨论,提出利用检测绕组电流及母线电流对系统进行故障检测。为使系统能够可靠运行,分析了功率电路、电机绕组、位置传感器等的故障现象,并且提出根据不同故障选择系统工作状态。
The redundancy control method of a kind of PMSM with backup windings was discussed, and a way to check the error in this system was introduced by checking the current of winding and bus bar. Error phenomenon in power circuit, motor winding and position sensor were analysed, and the ways of choosing system working state under different error for the reliable working of the whole system were recommended.
