Sensorless Control Method of Permanent Magnet Synchronous Motor Based on Kalman Filter
摘要
Abstract
Aimed at problems of high frequency ripple component exists permanent magnet synchronous motor (PMSM) parameter error caused by the sliding mode observer estimation error and counter electromotive force.However,a low-pass filter cannot eliminate the high frequency ripple,Therefore,the introduction of the Kalman filter to eliminate high-frequency ripple,making permanent magnet synchronous motor control system had better steady state performance and dynamic response.Then a MATLAB platform was built to validate this method,the experimental results showed that after the increase in the Kalman filter sliding mode observer not only robust,and to some extent inhibited the buffeting,there was some increase in the rapid and dynamic performance.关键词
