MPPT control strategy for photovoltaic cells based on fuzzy control

摘要

As output of photovoltaic batteries varies following the change to illumination, temperature and loads, it is necessary to do some researches on new control method of Maximum Power Point Tracking (MPPT) to guarantee high-efficiency output of photovoltaic batteries. In this document, a fuzzy control algorithm will be adopted to present steps to design fuzzy controllers. Simulation software MATLAB is utilized to establish simulation mockup for photovoltaic batteries, and executes the algorithm. Results of test indicate that simulation graphics can present good effects of static and dynamic tracking.
