摘　　要：电动车用感应电机参数变化易引起电机振荡现象,文中以含微分运算的三相感应电机模型为基础,提出了一种具有转差频率控制的转子磁场定向矢量控制方法,给出了相关的理论推导及实验结果。该方法能够有效地抑制由于电机参数变化过大导致的电机振荡现象,能使电机可靠地运行于弱磁区域,可满足高功率密度、高转速电动车用感应电机的控制要求。实验结果验证了该方法的正确性及有效性。Parametric variation of induction motor for electric vehicles will result in fluctuation of motor current and torque. A new field-oriented vector control method applying slip-frequency control is proposed, based on the three-phase induction motor model including differential operation. Theoretical derivation and experimental results are given in this paper. Applying this method can eliminate motor speed oscillation generated by severe parametric variation, and make motor run reliably in the field weakening range. The control scheme is completely adapted to meet the requirements of a high power and high-speed electric vehicle. The proposed method has been verified experimentally and proved to have good performance.
