Modeling and Analysis of a Fuzzy Type MPPT Algorithm

This paper presents a study on a MPPT (maximum power point tracker) which uses fuzzy control algorithm. Many algorithms were developed in the past few years to control the power obtained from a solar panel and optimize the panel performances in a large domain of functioning parameters. Fuzzy logic algorithms have the advantage they do not need a mathematical model for the solar panel in order to implement the controller. A fuzzy controller for a solar panel is obtained, implemented in MATLAB/SIMPOWERSYS and its functioning is studied by numerical simulations. Good results were obtained, power consumed by the load being very close to maximum power solar panel can achieve. That means this type of MPPT keeps the solar panel very close to the optimum functioning point.
