Abstract：Due to the changes of the motor parameters,the speed tracking system of permanent magnet synchronous motor(PMSM) will appear fluctuation. In order to deal with the problems,this paper presents a control strategy which unifies fuzzy control with backstepping control to deal with this problem. By the fuzzy controller adjusting backstepping parameters of the system,the method will improve the system speed tracking performance. The method is able to realize complete decoupling of the PMSM system,and ensure the control system global asymptotically stable. Moreover,by the fuzzy controller on real time adjusting the backstepping parameters,the system can realize fast speed tracking when the parameters of the motor have changed. The control system also can get a good robustness and servo performance. The simulational and experimental results verify the efficiency and feasibility of the system design.
