Fuzzy - PI Based MPPT Control for Photovoltaic Systems

Maximum power point tracking is one of the major functions of photovoltaic system because of the performance of photovoltaic system directly affected by atmospheric conditions. In this study, a DC-DC converter structure based on fuzzy-PI controller is proposed for maximum power point tracking to validate the performance of this configuration, a simulation model is realized by using Matlab/Simulink environment. Proposed fuzzy -PI controller has a superior performance against to classic PI controller under varying atmospheric conditions.
