中文摘要：
从阻抗视角分析光伏系统MPPT问题。基于对含源单调连续型非线性一端口网络的研究，引入误差调节的概念，提出一种光伏发电MPPT控制的自寻优算法。该算法可将非线性极值跟踪控制问题转化为线性误差调节问题。在lkW光伏发电实验平台上的实验证实了该算法的有效性。
英文摘要：
The subject of the maximum power point tracking of PV system from the impedance angle was analyzed. Based on the study of the monotonous continuous nonlinear network with source and one port, leads into a concept of error adjustment, a self-optimizing algorithm of PV MPPT control was presented. The algorithm can transform nonlinear extreme value tracking control problem into regulation of the linear error. The experiment that completed in the 1 kW experimental platform confirms the validity of the algorithm.
