摘　　要：基于机电能量转换原理,阐明了转子磁场定向控制不仅能实现电磁转矩和磁链的解耦,还能实现转子变压器电动势和旋转电动势的解耦,通过控制旋转电动势达到控制转矩和转速。针对电动汽车的感应电动机采用旋转电动势控制技术构成矢量控制系统,仿真表明这种新型的控制方法具有良好的动态性能,为提高电动汽车的控制性能提供了一条有效途径。Based on the principle of energy conversion, the rotor field-orientation control decouples not only flux linkage and electro-magnetic torque but also rotor transformer electromotive force and rotating electromotive force. The control of torque and speed can be achieved by controling rotating electromotive force. The vector control system based on control technology of rotating electromotive force is proposed for electric vehicle. The results of simulation show that the new control method has good dynamic performance and is an effective way for improving control performance of electric vehicle.
