Parameter Identification of Surface Mount Permanent Magnet Synchronous Motor Based on Rotational Speed Disturbance
摘要
Abstract
In order to solve the identification error caused by parameter identification coupling in the on-line identification of surface-mount permanent magnet synchronous motor,the coupling relation of parameter identification from the view of motor mathematical model was analyzed.The coupling relation between the stator resistance and the rotor flux linkage of the surface-mount permanent magnet synchronous motor was verified by simulation.A method of on-line decoupling parameter identification based on recursive least square method for speed-perturbation was also proposed. In this method,on-line decoupling identification of q-axis and d-axis inductance,stator resistance and rotor flux linkage were realized by adding rotational speed perturbation method and recursive least square identification method. Experiments and simulations show that the injection of rotational perturbation can effectively realize decoupling identification.关键词
