摘　　要：电动车上驱动用的永磁同步电动机一般采用基速以下恒转矩、基速以上恒功率的控制方法。本文则用功率反馈(观测)方式完成电传动系统后功率链的动力控制,并通过试验说明它的正确性。在此基础上,进行绕组切换,即利用变结构进行扩速,研究并选定了绕组切换形式和对应的转速区域。最后给出了部分总体性能仿真结果,同时进行了分析。The method of constant torque below base speed and constant power up base speed is usually used in the permanent-magnet synchromotor for an electric drive vehicle.In the paper,power is controlled by the feedback(observer)of power in the back power chain of an electic transmission system and feasibility is proved by test.And then,speed expanding is carried out by winding change calling variable structure and winding change form and its rotational speed range are studied.Finally,some of total performance simulation results are showed and analyzed.
