基于模糊控制的光伏最大功率跟踪器

摘要

A photovoltaic (PV)maximum power point tracker is designed on the basis of fuzzy control.First,the maximum power point tracking (MPPT)algorithm is designed on the basis of fuzzy control and applied to the PV maximum power point tracker based on the BUCK circuit.Then,the load resistance parameter of the BUCK circuit is designed and fuzzy control rules are established.Finally,the MPPT experimental results are given under different weather conditions.%基于模糊控制和BUCK电路设计了一种光伏最大功率跟踪器。首先，基于模糊控制设计最大功率点跟踪算法，并应用于基于BUCK电路的光伏最大功率跟踪器中；然后，设计BUCK电路的负载电阻参数，制定模糊控制规则；最后，给出了不同天气条件下的最大功率跟踪实验结果。
