Optimized Design And Implementation of Fuzzy Controlled APF Based on PSO Algorithm

The simulation and experimental study of a fuzzy logic controlled, single-phase shunt active power filter to improve current source THD by compensating harmonics and reactive power required by a nonlinear load is presented. AFuzzy PI controller with an unified universe range which physically related to classical PI controller is used. The fuzzy control scheme is realized on a micro-controller (lpc-1768 ).The objective of this paper is to design and implementation a Fuzzy PI controller using Mamdani method for a single phase APF, and optimizing it by using PSO algorithm to find the optimum range of fuzzy sets
