非线性系统无限网络的基于李雅普诺夫的ISS小增益定理

A Lyapunov-based ISS small-gain theorem for infinite networks of nonlinear systems

Christoph Kawan, Andrii Mironchenko, Majid Zamani

摘要:

在本文中,我们证明了一个无限网络的输入状态稳定(ISS)的子系统,承认ISS李雅普诺夫函数,本身也承认一个ISS李雅普诺夫函数,提供了子系统之间的耦合是足够弱的。耦合的强度用从互连增益建立的无限维非线性正算子的性质来描述。如果该算子诱导出一个一致全局渐近稳定(UGAS)系统,则可以构造该无限网络的李雅普诺夫函数。我们分析了UGAS的充要条件,并将它们与有限网络稳定性分析中使用的小增益条件联系起来。

英文摘要:

In this paper, we show that an infinite network of input-to-state stable (ISS) subsystems, admitting ISS Lyapunov functions, itself admits an ISS Lyapunov function, provided that the couplings between the subsystems are sufficiently weak. The strength of the couplings is described in terms of the properties of an infinite-dimensional nonlinear positive operator, built from the interconnection gains. If this operator induces a uniformly globally asymptotically stable (UGAS) system, a Lyapunov function for the infinite network can be constructed. We analyze necessary and sufficient conditions for UGAS and relate them to small-gain conditions used in the stability analysis of finite networks.
