提出了一种新的光伏系统最大功率跟踪模糊逻辑控制器。讨论了PV建模。传统的爬山最大功率点跟踪器的结构和功能进行了研究。新的控制器改进了爬山搜索方法，通过模糊化这些技术的规则，并消除其缺点。基于模糊逻辑的爬山提供了快速和准确的收敛到最大工作点在稳态和变化的天气条件相比，传统的爬山。仿真和实验结果证明了所提出的基于模糊逻辑的控制器的有效性。
A new fuzzy-logic controller for maximum power point tracking of photovoltaic (PV) systems is proposed. PV modeling is discussed. Conventional hill-climbing maximum power-point tracker structures and features are investigated. The new controller improves the hill-climbing search method by fuzzifying the rules of such techniques and eliminates their drawbacks. Fuzzy-logic-based hill climbing offers fast and accurate converging to the maximum operating point during steady-state and varying weather conditions compared to conventional hill climbing. Simulation and experimentation results are provided to demonstrate the validity of the proposed fuzzy-logic-based controller.
