Sensorless Control of Permanent Magnet Synchronous Motor Based on Least Square Algorithm
摘要
Abstract
A new rotor position and speed observer of permanent magnet synchronous motor was proposed based on the least square algorithm to accurately estimate the rotor position and speed and achieve sensorless control. Observer used the voltage equation in the synchronous rotating coordinate system, saw the voltage and current as the information variables and the rotor speed as parameter variables, used identification model of the least squares algorithm for online identification of the speed. The algorithm was simple and the computation cost was small. The results of MATLAB simulation showed that this control method was effective with its rapid response speed and strong robustness.关键词
