Abstract

A fuzzy-logic controller based on hill-climbing method for maximum power point tracking of photovoltaic system is proposed. The features of maximum power point tracker based on conventional hill-climbing algorithm are studied. The new controller incorporates the advantages of hill-climbing algorithm and eliminates its drawbacks. This technique provides fast and accurate convergence to the maximum power point during steady-state and gradually changing weather conditions. The hill-climbing algorithm is implemented using 17 fuzzy control rules. Simulation results are provided to illustrate the validity of the proposed hill-climbing based fuzzy-logic controller.
