Sensorless Control of Permanent Magnet Synchronous Motor Based on Extended Sliding Mode Observer
摘要
Abstract
Aiming at the chattering problem arising from the estimation of rotor velocity by using traditional sliding mode observer(SMO),the paper combines sliding mode control with model reference adaptive systems by the extended state equations of permanent magnet synchronous motor(PMSM) and the equations of extended sliding mode observer of PMSM,and then the new estimation method of rotor velocity is presented.The detailed comparison between the proposed method and the traditional one is introduced according to simulation analysis and experimental validation.The simulation and experimental results show the superiority of the proposed method which avoid the chattering problem of the traditional one and better estimated precision,moreover,good dynamic and static performance are achieved.关键词
