PERFORMANCES OF TORQUE TRACKING CONTROL FOR DOUBLY FED ASYNCHRONOUS MOTOR USING PI AND FUZZY LOGIC CONTROLLERS
In this paper a performances of torque tracking control for Doubly Fed Asynchronous Motor (DFAM) using PI and fuzzy logic controllers is proposed. First, a mathematical model of the doubly fed asynchronous motor written in an appropriate d q reference frame is established to investigate simulations. In order to control the rotor currents of DFAM, a torque tracking control law is synthesized using PI controllers, under conditions of the stator side power factor is controlled at unity level. The performances of fuzzy logic controller (FLC) which is based on the torque tracking control algorithm are investigated and compared to those obtained from the PI controller. Results obtained in Matlab/Simulink environment show that the FLC is more robust, superior dynamic performance and hence found to be a suitable replacement of the conventional PI controller for the high performance drive applications.
