摘要
设计了一种基于模糊控制的光伏阵列最大功率跟踪(MPPT)方法。以光伏阵列输出功率和输出电压之间满足dPPV/dUPV=0达到最大功率点为基础,设计了模糊控制的方法。利用仿真和实验,对比了扰动观察法和所设计的模糊控制法的性能,验证了该方法具有MPPT速度快以及稳态功率波动小的优点。
A maximum power point tracking （MPPT） method based on fuzzy logic control is designed.On the basis of the following facts that MPPT is realized when the relationship between output power and output voltage for the photovoltaic array is dPpv/dUpv=0,the fuzzy logic controls are designed.The simulation and experimental results verified that compare with the perturbationed observation method （P＆O） ,the designed method has the advantages of tracking the maximum power point quickly and less power fluctuation.
