针对基于二维模糊控制的光伏系统最大功率点跟踪（MPPT）控制方法在外界环境急剧变化时响应较慢、输出不够平稳等不足,提出了改进的模糊控制算法.该算法在传统二维模糊控制的基础上增加了一个反馈输入量,改善了系统的动态性能.仿真结果表明,与二维模糊控制及常规扰动观察法相比,改进的模糊控制不仅能快速响应外界环境的变化,而且具有较好的控制精度.

Under the situation of intensely variable environment,Maximum Power Point Tracking(MPPT) control method based on traditional fuzzy algorithm has disadvantages of slow response,unstable output and so on.To solve those problems,a modified fuzzy control algorithm was proposed.The method improves dynamic performance of system by adding a feedback input variable based on traditional fuzzy control method.The simulation results show that the proposed algorithm can not only rapidly respond to changes in ambient environment but also possess a better controlling accuracy,compared with the traditional fuzzy control method and perturbation and observation method.
