Disturbance Feed-Forward Compensation for High-Speed Permanent Magnet Linear Synchronous Motor Based on Extended Kalman Filter
摘要
Abstract
A disturbance feed-forward compensation method based on extended Kalman filter (EKF) was proposed for permanent magnet linear synchronous motor (PMLSM) servo system which is vulnerable to influence of the external disturbance, such as friction force and force ripple. Firstly, disturbance model which consists of position dependent functions was developed and utilized as a disturbance feed-forward compensator. And then, the initial position of the translator was estimated by the EKF and reflected to the disturbance feed-forward compensator. Also, the coefficients of the disturbance model were adjusted adaptively to create synchronization between the model and real disturbance and compensate system disturbance. Finally, the system simulation and experimental results confirm that the proposed scheme is effective and feasible. Compared with the disturbance observer, PMLSM servo system based on EKF has superior performance in disturbance compensation.关键词
