For asynchronous motor parame ter variations cause inaccurate speed estimation problem,an identification of the stator resistance and speed of both interactive model reference adaptive estimation methods,and the conventional model reference adaptive method has PI gain coefficients of complex problems in the estimation,using sliding mode control approach based on the rate to replace the PI link.This method only detects the stator side voltage and current values can be estimated during the run asynchronous motor stator resistance and speed values.The whole system has strong robustness to variation of the stator resistance,and improves the control precision of the whole system.To verify the accuracy of the proposed method for asynchronous motor by vector control simulation experiment.
