Coordinated Control of PMSM Sliding Mode and Active Disturbance Rejection Based on Fuzzy Rules
To solve the problems of slow response,large overshoot,and poor anti-disturbance ability of permanent magnet synchronous motor(PMSM)with traditional sliding mode control,a coordinated con-trol strategy was proposed in this paper.Based on the traditional exponential sliding mode,an improved sliding mode algorithm with a variable reaching law was designed,and a coordinated control strategy was constructed in combination with active disturbance rejection control.A variable control factor was obtained by using fuzzy control to adjust the proportion of active disturbance rejection in the system.A simulation and physical experiment platform was built for experiments.The experimental results show that the response speed of the system is significantly improved by the coordinated control strategy,the tracking without overshoot is realized,and the anti-disturbance ability of the system is enhanced.
