基于simulink powersystem元件库提供的光伏电池模型建立了扰动观测法的最大功率跟踪控制模型（MPPT），仿真模型能够很好的追踪最大功率点(Based on the photovoltaic cell model provided by Simulink powersystem component library, the maximum power tracking control model (MPPT) of disturbance observation method is established. The simulation model can well track the maximum power point)
