FPGA-based implementation of a fuzzy controller (MPPT) for photovoltaic module

This paper describes the hardware implementation of a two-inputs one-output digital Fuzzy Logic Controller (FLC) on a Xilinx reconfigurable Field-Programmable Gate Array (FPGA) using VHDL Hardware Description Language. The FLC is designed for seeking the maximum power point deliverable by a photovoltaic module using the measures of the photovoltaic current and voltage. The simulation results obtained with ModelSim Xilinx Edition-III show a satisfactory performance with a good agreement between the expected and the obtained values.

Research highlights
► FL-MPPT controller is implemented on FPGA.
► Results obtained with ModelSim show a satisfactory performance.
► Results will be useful for future development in PV.
