This paper presents the optimization of shunt active power filter parameters based
on fuzzy logic control. The current active filter control is based on constant, fuzzy hysteresis
band techniques, which are employed to derive the switching signals and also to
choose the optimal value of the decoupling inductance. The DC voltage controller optimizes
the energy storage of the DC capacitor, where proportional integral and fuzzy
logic controllers are employed. Simulation results, obtaining using MATLAB/SIMULINK
under several loads configurations, are presented and discussed. They show the
effectiveness of fuzzy logic controllers in optimizing the PWM technique and the values
of the passive parameters of the active filter.
