摘　　要：在感应电机数学模型的基础上 ,分析了在转子磁场定向恒磁通矢量控制感应电机控制系统中转子电阻和电机电感变化的影响 ,证明了电机电感的变化对电机转速和电磁转矩不产生影响 ,建立了考虑电机参数变化时电机矢量控制的数学模型 。Based on the induction motor mathematical model, the pa per analyzed the effects of inductance and rotor resistance variation in the mag netic field oriented constant flux induction motor vector control system and pro ved that inductance of the motor has no effects on the characteristics of the mo tor speed and magnetic torque. A mathematical model was set up considering varia tions of inductance and rotor resistance for vector controlled induction motor. The theoretical analysis and computer simulation results show that the model is effective and simple.
