针对光伏器件输出功率的非线性特性且工作环境变化频繁的特点，为了获得更好的最大功率点跟踪控制效果，对光伏电池功率电压曲线进行了分析，设计了一种基于遗传算法的模糊控制算法，解决了光伏器件特性在最大功率点两侧不同区间的差异问题，使系统能快速响应外界环境的变化，保证了系统的控制精度，光伏系统始终工作在最大功率点。通过仿真将模糊MPPT控制与基于遗传算法的模糊MPPT控制性能作了比较，结果表明控制性能良好。

Based on the nonlinear of the photovoltaic device output power and the frequent changes in the work environment, a fuzzy controller with genetic algorithm was applied to maximum power point tracking (MPPT) of photovoltaic generation system. The problem of difference in the different interval of the maximum point was solved. It ensured that the system has a higher accuracy .By comparing the method of the fuzzy control and the method of fuzzy control with genetic algorithm through simulation ,the result demonstrated the better control effect.
