Abstract :
The authors propose a fuzzy, current-controlled, pulse-width modulation (PWM) which minimizes current ripple using fuzzy set theory at a constant switching frequency. This technique is applied to an electrical drive system with an induction motor and studied by simulation. The results show that the technique performs better than classical methods such as ramp comparison and the hysteresis band control method
