Application of multirate Extended Kalman Filter to speed estimation of PMSM
摘要
Abstract
Permanent Magnet Synchronous Motor(PMSM)has some excellent features, such as fast response, better accuracy, high torque to current ratio. And meanwhile simplification and robust of PMSM can be improved by the research of sensorless control strategy. A PMSM input multirate EKF is proposed based on an analysis on algorithm of Extended Kalman Filters(EKF)and multirate digital control systems. The algorithm is applied to speed estimation for induction motor. Simulation and real-time experiment results reveal that the proposed algorithm has better abilities in identification accuracy and astringency stability than a singlerate EKF does, and almost has the same identification result with the high frequency singlerate EKF. However the proposed algorithm need less data and operation than singlerate EKF.关键词
