Fuzzy Logic Control for Speed of Wound Rotor Induction Motor With Slip Energy Recovery
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. Control speed by adjusting resistance value in the rotor circuit that occurs the efficiency of power are reduced, because of the slip energy is lost when it passes through the rotor resistance. The control system is designed to maintain efficiency of motor. Fuzzy logic control method is applied for self-tuning the system by keeping the speed constant and adjusting the rotor current appropriated to the load. The good transient response without overshoot can be obtained.
Keywords: fuzzy logic control, wound rotor induction motor, slip energy recovery.
