یک کنترل کننده منطقی فازی برای درایو موتور القایی کنترل شده بردار

In this paper, a novel fuzzy logic controller is proposed for vector controlled three phase induction motor. Modelling of the three phase induction motor is done with the help of governing modelling equations. Initially PID controller is interfaced with the induction motor model. Performance of the induction motor with PID controller is analysed under disturbance environment. Speed controller action of this PID controller is found to be poor under disturbance environment. Besides, fuzzy logic based speed controller is interfaced with the three phase induction motor. Performance of the induction motor with fuzzy logic controller under disturbance environment is examined. This fuzzy logic controller overcomes the drawbacks of the conventional PID controller. Tracking performance of this fuzzy logic controller is scrutinized in the disturbance environment. Superior speed controller action is achieved by the proposed fuzzy logic based speed controller for the three phase induction motor.
