| Abstract: | Output characteristic of the pohotovoltaic（PV） cell and the principle of maximum power point tracking（MPPT） were introduced.Based on the feature of the（PV） cell,fuzzy parameter self-tuning digital PID controller was proposed to realize its MPPT.PV energy generation system could track the maximum power of PV cell rapidly by using digital PID.Simulation and experimental results showed that the system had the robustness and the advantages of rapid response. |
