摘要
为了兼顾MPPT系统的快速响应和高精度的问题,文章提出了一种新型的模糊复合算法。首先给出了等效模糊模型复合的控制方法,然后采用在线学习的形式来不断改进模型以逼近真实模型。验证结果表明,算法具有良好的鲁棒性和适应性,能够使光伏发电系统稳定、高精度地工作在最大功率点附近。
In order to take into account both quick response and high precision in MPPT control system, a new fuzzy composite algorithm is put forward in this paper. Firstly, a composite control method of equivalent fuzzy model is given. Secondly, online learning is used for improvement of the model to approximate to the real model. The experimental results show that this algorithm has good robustness and adaptability. The photovoltaic power generation system with the algorithm can work steadily at the maximum Dower ooint.
