Aiming at non-linear model of multivariable induction motor, traditional PI method is hard to achieve satisfactory control purpose. Fuzzy control can carry the real-time control on system without the accurate mathematical model of induction motor. This paper elaborates induction motor vector control system and the basic principle of the fuzzy PI, making use of fuzzy reasoning, automatically adjusting the controller’s parameters. Simulation results prove that fuzzy PI controller is superior to traditional PI controller in the aspect of response speed, steady state accuracy and disturbance attenuation.
