摘　　要：针对光伏电池最大功率跟踪(MPPT)常用算法在跟踪速度和跟踪精度之间的矛盾,提出模糊控制策略,通过Matlab/Simulink搭建了光伏发电系统模糊控制算法仿真模型。通过仿真分析证明,该模糊算法能够迅速响应并有效减小最大功率点附近的振荡,最大限度地提高光伏电池的输出功率。该算法简单、灵活且跟踪效果好。The output power of the photovoltaic （PV ） cell has the single peak , the maximum power point tracking （MPPT） is essential to make the PV cell always work in maximum power point （MPP） ,and to improve the efficiency of PV system .In order to eliminate the contradiction between the tracking speed and the tracking accuracy ,the fuzzy control strategy was proposed .The packaging model of PV cell ,fuzzy controller and the MPPT simulation model of fuzzy control algorithm had been established .The simulation results show that the fuzzy control can track the MPP rapidly and reduce the oscillation power loss effectively ,maximizing the output power ,the fuzzy algorithm is simple and flexible and has better tracking effect .
