Abstract：In vector control system of PMSM, current controller performance will decline significantly because of changes in motor parameters, an on-line adaptive control of PMSM current-loop based on parameter identification is proposed. First stator resistance and permanent magnet flux linkage are identified using recursive least squares method with forgetting factor, and then d-q axis inductance are estimated using the same method base on the previous step, finally the PI parameters in real-time operating conditions could be obtained. Experimental results show that PI parameters can effectively adapt to change in working conditions and quickly achieve precise control of current.
