介绍了光伏电池的基本特性和最大功率点的原理及其运用的一些常规方法。针对模糊控制具有适应性强、鲁棒性好、不依赖被控对象精确模型的特点。提出了规则生成、模糊决策与推理。在此基础上建立仿真模型，对模糊控制器进行验证和分析。仿真结果表明，当外部环境发生变化的时候，系统能够迅速跟踪此变化，使系统始终工作在最大功率点附近，并具有较好的稳定性，且基于模糊策略的光伏系统动、稳态性能优良。%Introduction was made to basic characteristics of the photovoltaic cells and the maximum power point principle and some regular methods of its application. Aiming at features of fuzzy control with strong adaptability, good robustness and independent of the controlled object accurate model, this paper proposed rules generation, fuzzy discussion making and reasoning. On the basis of this, the simulation model was established and the fuzzy controller was carried out rectification and analysis. The simulation result shows that on change of external environment, the system can quickly trace the change, making system always working around maxi-mum power point with fine stability and dynamic stability performance is fine for photovoltaic system based on fuzzy strategy.
