摘　　要：在Matlab仿真环境下建立了一个基于Boost拓扑的光伏充电器,并且引入模糊控制技术对该仿真模型进行最大功率点跟踪(MPPT)控制。不仅从标准测试条件、光照突变这两种情况来比较模糊控制跟踪策略与爬坡法、电导增量法的区别,还从温度持续上升、光照持续上升、采样时间间隔这三方面,对三种跟踪策略进行比较,能够更全面地证明模糊控制跟踪策略在响应速度以及稳定性上优于爬坡法和电导增量法。A photovoltaic charger with Boost topology in the Matlab was set up,which introduced fuzzy controlling technology to implement maximum power point tracking.The differences among the fuzzy control method,the climbing hill method and the conductance increment method were analyzed not only by the normal testing condition and the solar radiation changing suddenly but also by the temperature ascending continuously,the solar radiation ascending continuously and the distance of the sampling time.And it could prove the responsibility and the stability of the fuzzy control method better than those of the climbing hill method and the conductance increment method.
