针对目前光伏系统最大功率点跟踪(MPPT)技术研究和应用现状,相对占空比扰动法,提出一种用于最大功率点跟踪的模糊控制算法,建立系统控制模型,并用Matlab/Simulink进行系统整体仿真,验证了当外界环境变化时,模糊控制法具有MPPT速度更快以及稳态功率波动更小的优点.%In view of the present research and application status of current maximum power point tracking ( MPPT) , and in relation to duty factor made by perturbation method, a new method based on fuzzy logic control was proposed in this paper. A system control model was established and Matlab/Simulink was used to simulate the whole system. The MPPT controller based on fuzzy control was used to make sure that the MPPT can be more rapidly tracked with less power fluctuation when the external ambient temperature changes.
