摘　　要：采用带有学习能力的模糊逻辑控制与数字PID控制相结合的手段对光伏组件进行最大功率点跟踪,通过在MATLAB/Simulnk软件环境下建立仿真模型,与传统的扰动观察法进行对比实验.实验结果表明,自适应模糊逻辑PID控制技术很好地解决了扰动观察法精度不高、响应慢、适应性差的缺点,改善了系统的动态特性和稳态性能,可以较好地提高光伏发电的能源利用率.In this paper,the combination of fuzzy logic control with learning ability and digital PID control has been used to track the maximum power point of PV system.The simulation model has been established in the MATI.AB/Simulnk software,and compared with the results of the traditional per turb and observe method.The experimental results show that the self adaption fuzzy logic PID control technology can solve the shortcomings of low accuracy, slow response and poor adaptability of the per turb and observe method, improve the dynamic characteristics and steady state performance of the sys tern,also, improve the energy efficiency of photovoltaic power generation.
