Disturbance observation combined with fuzzy control in MPPT algorithm

随着化石能源的不断消耗,人类面临着巨大的能源危机,太阳能作为一种新能源越来越受到重视。分析了光伏电池板的数学模型,针对光伏电池板输出特性及最大功率点的跟踪方法,主要介绍了模糊控制的扰动观察对最大功率点跟踪的影响。利用Matlab仿真软件对电路进行仿真,验证了模糊控制的扰动观察能减少最大功率点附近震荡的功率损耗,且具有跟踪速度快等优点。

With the continuous consumption of fossil energy, mankind faced with the huge energy crisis, solar energy as a new kind of energy received more and more attention. The mathematical model of PV panels was analyzed. According to the output characteristics of PV panels and the maximum power point tracking, the fuzzy control of perturbation and observation on the effect of maximum power point tracking were mainly introduced. Using Matlab simulation software of circuit simulation, the perturbation and observation method of fuzzy control were verified which could reduce the power loss near the maximum power point concussion, the advantages of fast tracking were possessed.
