摘　　要：提出一种基于模糊自寻优控制的农田独立光伏供电最大功率点跟踪(MPPT)控制。首先构建太阳能MPPT检测装置系统,在实验仿真基础上,现场测试模糊自寻优控制法与传统模糊控制法跟踪MPP实际控制效果,进行功率输出控制的对比试验。实验结果表明该控制方法与传统模糊控制法相比提高输出功率6%,并具有良好的动静态性能和鲁棒性。A kind of optimal control mode based on fuzzy self-optimizing maximum power point tracking （MPPT） control in a stand alone PV power station of farmland was put forward. Solar MPPT detection device was built up based on the experimental simulation, then the actual tests were carried out to compare the adaptive fuzzy optimization control method with the traditional fuzzy control for the MPP tracking control in the experiment of power output. The experimental results show that the power output of former improved control is 6% higher than that of later statistically, and the method has better dynamic and static performance and robustness.
