Fuzzy logic controlled buck-boost DC-DC converter for solar energy-battery system

In this paper, a Fuzzy Logic Controlled (FLC) buck-boost DC-DC converter for solar energy-battery systems is presented. General design of a fuzzy logic controller (FLC), based on Matlab/Simulink is performed. This design compared with Proportional Integrated (PI) controller. The complete control system has been developed, analyzed, and validated by simulation study. Performances have then been evaluated in detail for different study conditions.
