静止条件下的异步电机参数辨识方法研究

Research on the methods for parameters identification of induction motor at standstill

针对电机停机状况下需要对电机进行参数辨识的特殊要求,研究了静止条件下异步电机定子电阻、转子电阻、定子电感、转子电感及互感等参数的辨识方法.实验结果表明:采用该方法得到的电机参数应用于无速度传感器矢量控制系统,系统运行稳定.

To the special requirement for parameters identification of induction motor when motor keeps quiescent, a new method for parameters identification of induction motor was presented. The parameters include the stator and rotor resistance, the stator and rotor inductance and magnetizing inductance. The experiment results show that when sensorless vector control system uses motor parameters got by this method,it can run stably, so parameters got by this method are reliable and has good performance of anti-jamming.
