This paper presents the speed control scheme of indirect vector controlled induction motor (EVI) drive. Voltage source inverter type space vector pulse width modulation (SVPWM) is used for PWM controlling scheme. An intelligent based on Fuzzy PI controller is developed for controlling the torque component Iq current of an EVI. The complete vector control scheme of the IM drive incorporating the FLC is experimentally implemented using a digital signal Peripheral Interface Controller dsPIC 30F4011 for the laboratory 1-hp squirrel-cage IM. The performances of the proposed FLC-based IM drive are investigated and compared to those obtained from the conventional proportional-integral (PI) controller-based drive both simulated and experimentally at different dynamic operating conditions such as step change in command speed and load change. The comparative results show that the FLC is more robust, found to be a suitable replacement of the conventional PI controller for the high-performance industrial drive applications.
