Abstract :
Fuzzy logic control is considered for speed of wound rotor induction motors with slip energy recovery. The speed is limited at some range of sub-synchronous speed of the rotating magnetic field. By controlling speed by adjusting the resistance value in the rotor circuit the efficiency of power is reduced, because of the slip energy lost when it passes through the rotor resistance. The control system is designed to maintain efficiency of the motor. A fuzzy logic control method is applied for self-tuning the system by keeping the speed constant and adjusting the rotor current appropriate to the load. Good transient response without overshoot can be obtained
