提出一种应用于光伏发电系统中的基于中值观测的自适应变步长MPPT方法。该MPPT方法以中值法为观测基础，具有自适应且变步长的优势，跟踪过程不需要人为干涉与寻找初值和优值，在具有高效率的同时具有很高的适用性。在Matlab/Simulink平台验证了此MPPT控制算法，其模型避免用到除法器，有利于加快运算速度与减小电路规模。

s:An adaptive variable-step MPPT(maximum power point tracking)algorithm based on mid-value observation is proposed,which is applied to the photovoltaic power generation system. It bases on mid-value observation and owns the advan-tages of adaptive variable-step. It does not need any man-made interference or define parameters during tracking. Its high effi-ciency and applicability are outstanding. This MTTP algorithm is verified in Matlab/Simulink platform. There is no divider in the model,so it is beneficial to accelerate tracking and simplify circuit.
