针对在太阳能光伏发电系统中模糊控制算法对最大功率点进行跟踪时的特点，设计了一种改进型的控制算法。其采用模糊控制法与电导增量法算法相结合，使得工作点进一步接近最大功率点，并且有效减小了在最大功率点的振荡。通过对单一的模糊控制法、电导增量法和模糊控制法与电导增量法相结合算法的仿真对比，结果表明该结合算法可以在外界环境急剧变化的情况下能快速，准确地跟踪到最大功率点处，同时有效减少了在光伏电池阵列最大功率点附近的振荡，提高了光伏发电效率。

An improved control algorithm was designed, through tracking MPPT using fuzzy control algorithm in the solar photovoltaic. And the operating point was closer to the maximum power point, and oscil ation at the maximum power point was effectively reduced. The results show that it could track the maximum power point quickly and accurately in the case of rapidly changing environment, using Incremental Conductance combined with fuzzy control algorithm. Meanwhile, the oscil ation in the vicinity of the maximum power point of the photovoltaic cel array was reduced, and the efficiency of PV was improved.
