基于扩张状态观测器的永磁同步电机无位置传感器控制
Linear Extended State Observer-based Sensorless Control for Permanent Magnet Synchronous Motors
摘要
Abstract
The permanent magnet synchronous motor(PMSM)drive equipped with sensors may experience reduced reliability and diminished anti-disturbance capabilities.In light of this,this paper introduces an advanced linear extended state observer(ILESO)based sensorless control approach.To enhance the estimation accuracy of rapidly changing back-electromotive force and bolster robustness,a proportional action in connection with the speed estimation error is integrated into the uncertainty observer.Furthermore,an enhanced phase-locked loop(EPLL)is employed to expedite the convergence rate of rotor position estimation error,particularly under ramp-changed disturbances.Finally,the efficacy of this control strategy is experimentally validated on a PMSM-Generator set.关键词
