Abstract |
The paper presents a fuzzy logic based shunt active filter both as regard the PWM inverter current
control and the capacitor energy management. Focus is addressed on reference computing with the
instantaneous powers theory improved by the introduction of a regulation factor which is inferenced
by a fuzzy controller. Moreover a fuzzy control acts on the inverter switches duty cycles ensuring an
optimum current tracking. The aim of this regulation is to face sudden changes of load power demand
during transients. To test the effectiveness of the proposed control, the active filter is applied to
compensate the distorted currents produced by a diode-rectifier front-end-type PWM-VSI induction
motor drive working in transient conditions. The simulation results highlight a very high reduction of
the line current harmonic distortion with an acceptable switching frequency and the good results
obtained, thanks to the fuzzy logic based control, even in transient conditions. |
