采用抗差扩展卡尔曼滤波器的感应电机转速估计方法
A Speed Estimation Method of Induction Motors Using the Robust Extended Kalman Filter
摘要
Abstract
Extended Kalman filter（EKF） is widely used in speed estimation of induction motors in sensorless vector control systems.Although EKF has a strong anti-interference ability,the filter is still unsteady with gross error.A speed estimation method of induction motors based on the robust extended Kalman filter is proposed in this paper,and the effect of gross errors on estimation accuracy of the extended Kalman filter is analyzed.Whether robust EKF can give better estimation performance and robust ability than EKF for speed estimation of induction machines is discussed.Through the simulation and experiments,the speed estimation error and the flux change coursed by external disturbance and estimation error based on robust EKF are compared with EKF.The simulation and experimental results show that robust EKF has the same estimation performance and better robust ability.关键词
