中文摘要：

本课题介绍了光伏电池的电气原理,并搭建了光伏电池的仿真模型。同时针对太阳能光伏发电系统的最大功率点跟踪（Maximum Power Point Tracking,MPPT）原理进行了详细的分析;然后设计了模糊控制器,提出了一种基于模糊控制的最大功率点跟踪策略;最后利用MATLAB/Simulink仿真,对比了扰动观察法和课题设计的模糊控制法的跟踪性能。实验表明,当外界环境剧烈变化时,该模糊控制法具有更优的跟踪速度,并且具有更好的稳定性。

英文摘要：

This paper introduces the electrical principle of photovoltaic cells and builds a simulation model of photovoltaic cells.And also, the principle of Maximum Power Point Tracking（MPPT）for solar photovoltaic power generation system is analyzed in detail.And then, this paper designs a Fuzzy Controller and puts forward the MPPT tracking strategy which is based on fuzzy control.Finally, by means of MAT- LAB/Simulink simulation, the tracking performances of Perturbation and Observation Method and the Fuzzy Control Method designed by the writer are compared in this paper.The experiment shows that when the external environment changes greatly, the Fuzzy Control Method has faster tracking speed and more stability.
