Research Into an Induction Motor Rotor Resistance Identification Strategy

针对矢量控制中转子电阻随温度变化 ,导致用于滑差计算的转子电阻和其的实际值不一致 ,破坏磁通和转矩的解耦条件的问题 ,对一种转子电阻在线辨识策略进行了研究。这种方法的优点是简单准确 。

The rotor resistance changes widely with the rotor temperature, resulting in various harmful effects such as destruction of the decoupled condition of the flux and torque. This paper discusses a strategy for the identification of the instantaneous value of the rotor resistance. This strategy has the advantage of directness and correctness, the computer simulation proves its effectiveness and correctness.
