| 摘 要： | 通过研究光伏发电系统的最大功率点跟踪算法，分析光伏电池的输出特性。根据分析结果，提出一种基于变论域模糊滞环理论的最大功率点跟踪控制方法。该方法能快速感知外部环境变化，有效消除采用单一模糊控制带来的在最大功率点附近振荡的问题，减少了能量流失。实验结果证明，该方法能使光伏系统稳定在最大功率点处工作，消除了振荡，提高了转换效率。

| Abstract: | Maximum power point tracking （MPPT）algorithm for photovoltaic generation system is researched. The output characteristics of photovoltaic cell are analyzed. Based on the results,variable universe fuzzy hysteresis comparison method is introduced for MPPT of photovoltaic generation system,which can track the maximum power point of photovoltaic cell rapidly when the environment changes quickly,effectively eliminate maximum power point （MPP）oscillation problem brought and reduce by single fuzzy control energy loss. Experimental results show that the proposed method tracks MPP exactly and quickly,eliminates the oscillation,and greatly improves energy con-version efficiency. |
