基于滑模速度控制器的PMSM无速度传感器控制研究
Research on Sensorless Control of PMSM Based on Sliding Mode Speed Controller
摘要
Abstract
A method based on extended kalman filter( EKF) of permanent synchronous motor without position sensor was proposed due to the mechanical sensor problem exiting in traditional PMSM vector control system. At the same time varying load and parameter variations also affect the stability of the whole control system, so a sliding mode controller was used to replace the traditional PI controller. At first, linearizing mathematical model of PMSM,then using extended Kalman filtering algorithm to estimate speed and position, at last, designing speed error as the state variables of the sliding mode speed controller to realize closed-loop control. The simulation results showed that the EKF could estimate the rotor speed and position effectively and system has faster response、better anti-interference performance and stronger robustness under the action of sliding mode speed controller.关键词
