Fuzzy PI Gains Tuning By PSO And Genetic Algorithms Controls A Hybrid Indirect Matrix Converter

Abstract

In this paper, we study the performance of a power active filtering of the current perturbation using a hybrid indirect matrix with a three cell flying capacitance; this hybrid structure is controlled by a fuzzy PI controller in which it gains are tuned with the PSO algorithm and genetic algorithm (GA). In the first part, we present the full grid model with the perturbation source, as well as a detail of the hybrid structure. In the second part, we explain the current perturbation identification technique, and then we passed to gains tuning used algorithms. The simulation results by MATLAB, Simscap/sim power system code shows a good performance of the fuzzy PI gains tuning by obtaining a low THD value in the filtration process.
