dSPACE based Adaptive Fuzzy Controller of DC bus voltage for three-phase power filter

In this paper, new Adaptive Fuzzy Controller (AFC) of the DC bus voltage of three phase shunt active (APF) power filter is presented. The proposed adaptive fuzzy controller for APF, consist to adapt the output gain of this controller at every situation of the system as a function of the voltage error and its variation. The experimental results show the effectiveness of the designed active filter, associated with AFC and its capability improves the power quality by reducing the total harmonic distortion of the supply current.
