基于模糊控制的MPPT光伏发电系统

摘要

A MPPT photovoltaic power generation system with Boost topology in the Matlab/Simulink was set up.Accord-ing to the basic principle of maximum power point tracking (MPPT),a new fuzzy control algorithm is presented in this paper. The design steps of fuzzy control er were presented in the simulation.Results of this simulation were compared to those ob-tained by the modified perturbation and observation control er.%在Matlab／Simulink仿真环境下建立了一个基于Boost电路的最大功率点追踪（MPPT）光伏发电系统。根据最大功率点追踪的基本原理，提出了一种新的模糊控制算法。通过仿真环境详细描述了模糊控制器的设计过程，并将其仿真结果与改进型扰动观察法的仿真结果进行对比，验证了所提出的方法的跟踪速度更快，对环境温度变化更灵敏等优点。
