MPPT based on P&O control and FLC-Hill Climbing technique for a Photovoltaic Generator

This paper deals with a control of a photovoltaic generator using a maximum power point traking control which is an important function in all photovoltaic (PV) power systems through the conventional P&O method and the Hill-Climbing technique. It also presents an intelligent approach for the improvement and optimization of this control performances of a photovoltaic system, through the association of fuzzy logic control with the MPPT control. The simulation is developed under matlab/Simulink. different methods are used with a boost DC/DC converter. these results show us the efficiency and the robustness of a fuzzy logic based controller instead of the classical P&O controller.
