摘　　要：为提高电动汽车电传动系统性能,提出永磁同步牵引电动机直接转矩控制策略。根据电机的运行状态选择空间电压矢量获得快速动态转矩响应,同时有效降低逆变器的开关损耗。为提高系统效率,采用基于实时输入功率检测的定子磁链优化控制方法。仿真及实验结果证明了控制策略的有效性。In order to improve the performance of permanent magnet synchronous traction motor （PMSTM） in electric vehicle （EV） drive, a novel direct torque control （DTC） strategy is proposed. Based on the operating mode of PMSTM, zero voltage vectors are chosen to obtain quick dynamic torque response and reduce inverter switching loss. An optimization control method about stator flux linkage is presented to improve system efficiency, the core of which is the real-time regulation of stator flux linkage by measuring inverter input power. Simulation and experimental results prove the proposed strategy.
