| 摘 要： | 根据半桥升压式(half-bridge-boost)光伏并网逆变器的特点,分析了一种基于扰动观测的单传感器MPPT算法.在此基础上,将模糊控制与其结合,形成了扰动观测-模糊控制的单传感器MPPT算法,改善了系统的响应特性和稳定性.在Matlab/Simulink平台上与其他几种常用的算法进行仿真对比,结果表明基于扰动观测-模糊控制的单传感器MPPT算法跟踪速度快,在最大功率点附近振荡小,系统稳定.

| Abstract: | According to the characteristics of the photovoltaic inverter using half-bridge-boost,a single sensor MPPT algorithm based on disturbance observer is analyzed.On this basis,combing with the fuzzy control,a single sensor MPPT algorithm based on disturbance observe-fuzzy control is proposed to improve the responsibility and stability of the system.On the Matlab/Simulink platform,several commonly used algorithms have been simulated for comparison.The result shows that the single sensor MPPT algorithm based on disturbance observer-fuzzy control has high tracking speed,small oscillation near the maximum power point,and the system is stable. |
