Novel Technique for Induction Motor Speed Control Using Fusion Pid-Fuzzy Logic Controller

Induction motors are for the most part used in every industries. The speed of the induction motor has to be different according to application requirement. consequently, there is a require for further resourceful and reliable induction motor drive systems for modern and prospect applications. Induction motors are extremely non-linear systems, having uncertain time altering parameters mostly rotor resistance and subjected to unrevealed load disturbance. In accumulation, the rotor flux is unapproachable for state feedback control. captivating these complications into account, a variety of control strategies are proposed such as vector control method(VCM), direct torque control(DTC), and sliding mode control. The utilize of proportional plus integral (PI) controller for speed control of induction motor with greater than mention technique give practical performance in steady state operation. nevertheless, this performance categorized by an overshoot, slow transient rejoinder, steady state error and the main drawbacks of this variety of controllers is its understanding to difference in system's parameters and the fact that when with fixed gains the controller may not make available the required speed performance under variation in the motor load torque and operating circumstances. In order to conquer these challenge, novel fusion PID-Fuzzy Logic controller has been proposed for induction motor speed control.
