Abstract :
A fuzzy logic based output voltage selector is presented which allows the electromagnetic torque ripple in an induction motor employing direct torque control (DTC) to be reduced. Practical results are presented comparing the torque ripple when the new controller is employed with that obtained using conventional DTC
