摘　　要：针对异步电机参数变化导致转速估计不准确的问题,提出一种同时辨识定子电阻和转速的交互式模型参考自适应估计方法,并针对常规模型参考自适应方法在估计时存在复杂的PI增益系数调节的问题,使用基于趋近率的滑模控制来替代PI环节。该方法只需检测定子侧电压和电流值即可估计异步电机在运行过程中的定子电阻和转速的值,使整个系统对定子电阻的变化具有较强的鲁棒性,提高整个系统的控制精度。通过对异步电机的矢量控制仿真实验验证了该方法的准确性。For asynchronous motor parameter 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.
