The vector control system control system of PMSM fed by TSMC was researched. Vector control system of TSMC-PMSM based on Anti-Windup speed controller was presented in order to make up the insufficient of the Integral Windup phenomenon of PID controller which will cause the system overshoot and oscillation. The anti-windup control strategy can make the speed controller leaving saturation area as soon as possible. The simulation results show that the controller has the perfect effect in restraining windup phenomenon, reducing the system overshoot amount and improving the stability of the whole control system.
