    首先阐述了光伏电池的工作原理及其数学模型,根据数学模型在 MATLAB仿真软件中搭建了光伏电池的工程通用仿真模型。同时,根据生产厂家提供的参数,分析了光伏电池的输出特性曲线,研究了光照强度和环境温度对光伏电池的影响。其次介绍了 MPPT 控制算法的工作原理,比较了 4 种常用控制算法的优缺点,针对单一控制算法无法兼顾跟踪精度和响应速度的问题,分析了基于扰动观察法的模糊控制 MPPT 组合算法并提出了一种新型组合 MPPT 算法,即基于电压自寻优的扰动观察算法。(Firstly, the working principle and mathematical model of photovoltaic cells are described. According to the mathematical model, a general engineering simulation model of photovoltaic cells is built in MATLAB simulation software. At the same time, according to the parameters provided by the manufacturer, the output characteristic curves of photovoltaic cells are analyzed, and the effects of light intensity and ambient temperature on photovoltaic cells are studied. Secondly, the working principle of MPPT control algorithm is introduced, and the advantages and disadvantages of four common control algorithms are compared. Aiming at the problem that single control algorithm can not give consideration to tracking accuracy and response speed, the fuzzy control MPPT combination algorithm based on disturbance observation method is analyzed and a new combined MPPT algorithm, namely voltage-based, is proposed. Self optimizing perturbation observation algorithm.)
