| Abstract: | This paper presents a method for maximum power point tracking problem of PV system based on a fuzzy control.The model of the structures of photovoltaic arrays,analog circuits,and simulation of fuzzy controller model are set up in Matlab / simulink,which means to verify the fuzzy control method.When compared with the traditional fixed step of perturbation and observation method(P & O),this method can eliminate the oscillation around the maximum power point power loss,and has the advantages of tracking accuracy and response speed. |
