基于模糊控制算法的光伏电池MPPT设计

摘要

In this article,the characteristics of photovoltaic cells is described and the principle of maximum power point tracking（MPPT） of photovoltaic is analyzed.For PV cells with the characteristics of nonlinear and time delay,the fuzzy-control algorithm is proposed to approach the maximum power.Simulation results show that the system has good control performance.%介绍了光伏电池的特性,分析了光伏电池最大功率点跟踪（MPPT）的原理,针对光伏电池具有非线性和时滞性的特点,提出了一种模糊控制算法来跟踪光伏电池的最大功率点。仿真结果显示,系统具有良好的控制性能。
