Asymmetric Fuzzy Logic Controlled DC-DC Converter for Solar Energy system

Abstract

In this paper, a controlled voltage system for a solar energy source is presented, by a new command called fuzzy logic controller (FLC), via a DC-DC converter .The fuzzy logic control is selected due its performance and efficiency even for nonlinear systems such as the DC-DC converters. A simulation with MATLAB SIMULINK environment of the FL control system, compared with a classical PI controller, is presented at the end of the paper to illustrate the good behavior of the control.
