摘　　要：从理论及试验上深入地分析了定子电阻参数变化对定子磁链估计的影响。同时,在伪降阶磁链观测器的基础上提出了定子电阻、转子电阻及转速的参考模型自适应律,从实验结果可以看出电机参数依据本文所得到自适应律进行独立辨识时可以获得的估计精度。In this paper,the effect of the change of stator resistance parameters on the estimate of stator flux is analyzed theoretically and experimentally.Meanwhile,MRAS law of stator resistance,rotor resistance and speed is processed based on false reduced-order flux observation.The experiment result shows that the precision of estimate can be attained where the MRAS law found in the paper is applied to the unattached identification of motor parameters.
