this paper is about an induction motor which can be utilized the amount of speeds in a desired range with particular torque. If chosen controller is designed with fuzzy logic, several efforts should have been done to improve the controller performance for correct control and quick response. Purpose of designing this controller, is providing stability and reducing overshoot in response to disturbances and sudden changes in particular speed reference. In this paper, the method that is used for drive control is hybrid fuzzy control method, and is compared with the classic controllers and fuzzy controller. Advantages of this method are compared to other methods, and show the ability of better control. The erformance of varies controllers are compared by MATLAB simulation. The results show satisfied performance of proposed method.
