Abstract - In this paper a self-tuning fuzzy logic speed controller is proposed for the high performance drives of   induction   motor.   Here,   the   output   gain   of   the controller is adjusted on-line by fuzzy rules according to the current trend of the controlled process. Tuning of the output gain has been given the highest priority because of its strong influence on the performance and stability of the system. The ability of the proposed controller is verified in the presence of external load variations using MATLAB simulation with the comparison of conventional PI controller. Simulation results showed the effectiveness  and robustness  of the proposed approach.
