On-Line Adaptive Control of PMSM Current-Loop Based on Parameter Identification
摘要
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.关键词
