摘要
Abstract
Based on the permanent magnet synchronous motor(PMSM)for ship propulsion,the paper proposes an improved sliding mode observer to optimize PMSM speed control system control.The traditional sliding mode observer will produce the corre-sponding chattering problem when the back EMF is estimated,the paper adopts the new saturation function as the switching func-tion,designs the adaptive sliding mode gain to improve the stability of the observer.In view of the low-pass filter action,the system is prone to phase delay,a dynamic cut-off frequency low-pass filter is designed,and combined with the Kalman filter to further im-prove the system performance.Finally,combined with the Matlab simulation of the motor control system,the effect and superiority of the improved sensorless control system are verified.关键词
