摘要

针对降压变换器中最大功率点跟踪问题，提出了一类新颖的李雅普诺夫控制器。这里考虑的太阳能发电系统由连接到DC/DC降压转换器的独立光伏板组成。考虑依赖于输出的Lyapunov函数候选者来发展条件，在某些情况下，可以表示为线性矩阵不等式;这些条件保证输出渐近于零，从而意味着实现了MPPT。仿真和实时结果验证了该方法的有效性。

A family of Lyapunov-based control schemes for maximum power point tracking in buck converters

This paper presents a novel family of Lyapunov-based controllers for the maximum power point tracking problem in the buck converter case. The solar power generation system here considered is composed by a stand-alone photovoltaic panel connected to a DC/DC buck converter. Lyapunov function candidates depending on the output are considered to develop conditions which, in some cases, can be expressed as linear matrix inequalities; these conditions guarantee that the output goes asymptotically to zero, thus implying that the MPPT is achieved. Simulation and real-time results are presented, which validate the eﬀectiveness of the proposals.
