| Abstract: | Based on the property that the output power of photovoltaic cell varies with temperature of environment and intensity of sunlight, this paper puts forward an intelligent control method which adopts genetic algorithms to optimize control rules of fuzzy logic controller, and the control system is designed based on field programmable gate array （FPGA）. The experiment results show that the control system realizes rapid on-line evolution, tracks the maximum power point of photovoltaic cells in a quick and accurate way, and is self-adaptive. |
