Abstract: Perturbation observation is the simplest method in the maximum power point tracking for photovoltaic panel. But the method can not track the Maximum Power Point(MPP) quickly and exactly. This condition can be modified using perturbation observation method with fuzzy theory deciding the step size. Field Programmable Gate Array(FPGA) has the advantages of low cost and flexible design, so the EP2C8Q208C8N of Cyclone II was chosen to be the core of control system. According to the scheme, after the whole control system was built and the functions of divided parts were accomplished, the entire system that consists of designed parts was simulated to ensure that the design is correct. As can be seen from the results, the MPP is tracked quickly and efficiently in the present designed system.
