Abstract: Designed a fuzzy PI controller was by combined fuzzy control with conventional PID control.The simulation model of the permanent magnet linear synchronous motor(PMLSM)and the vector control system was built by Matlab/Simulink.Simulation results show that the fuzzy PI controller is superior to the conventional PI speed controller in dynamic stability performance,this method can reduce transient and stable thrust ripple and has strong robustness to load disturbance.
