In most of the industries, scalar controlled induction motors are widely used for the variable speed applications. Nowadays, for high performance applications, field oriented control (FOC) technique is prefered. But, detuning caused by disturbances in parameters and exterior load disturbances still limits the performance of these drives. In order to accomplish variable speed operation, conventional PID controller is commonly used which provides limited good performance over a wide range of operation. In this paper a vector controlled induction motor employing a Fuzzy Logic Controller (FLC) in the outer speed control loop is analysed. The scheme is simulated in MATLAB/SIMULINK and the performance of FLC based scheme is compared with those of PI controller based scheme.
