基于改进BSMC与ASMO的PMSM无感控制策略研究
Research on sensorless control strategy for PMSM based on BSMC and ASMO
摘要
Abstract
Due to the nonlinear,strongly coupling,and variable parameter characteristics of permanent-magnet synchronous motors(PMSM),it is difficult for PI controller to achieve excellent control performance.In order to address the poor dynamics,anti-disturbance,and robustness in the speed control of PMSM with PI controller,a control approach combining backstepping sliding mode controller(BSMC)and adaptive sliding mode observer(ASMO)is proposed.A non-ideal motion model for the speed control loop of PMSM is established.On this basis,a BSMC is proposed by means of virtual control variables and Lyapunov functions.In order to realize the sensorless control,the adjustment coefficients and adaptive rates are introduced,an improved adaptive sliding mode observer is proposed to obtain the speed and rotor position of the PMSM.The experimental comparison of the proposed method is conducted with the traditional PI controller in terms of dynamic characteristics,anti-disturbance performance,and robustness,and the results show that the proposed method has better performance.关键词
