CONTROL SYSTEM OF SOLAR CELL GENERATION USING GENETIC ALGORITHM AND NEURO FUZZY CONTROLLER

摘要

A control system of a solar cell generation is provided to control MIPPT(Maximum Power Point Tracking) through a neuro fuzzy controller in regardless of the change of MPP(Maximum Power Point). A control system of a solar cell generation includes a solar cell array(10), an electric power conversion unit(20), and MPPT controller(30). The solar cell array outputs DC signal corresponding to sunlight, the electric power conversion unit converts DC signal into AC or DC voltage. The MPPT controller includes an MPP estimation unit(30a) and a neuro-fuzzy controller(30b). The MPP estimation unit estimates MPP by measuring an output voltage and a current of the solar cell array. The neuro-fuzzy controller estimates and controls MPP automatically according to MPP change, the electric power conversion unit operates according to a control signal of the neuro-fuzzy controller.
