AI总结:

本文提出区域依赖的增益条件,用于解决传统小增益定理失效时的系统稳定性问题,通过局部渐近稳定性与全局吸引性保证原点稳定性,并通过两个例子展示方法有效性。

摘要:

一个系统稳定性充分条件由小增益定理给出。应用该定理需要增益组合连续、递增且上界小于单位函数。本文提出另一种充分条件,用于解决因缺乏连续性或增益上界大于单位函数而失效的情况。更精确地说,通过区域依赖的小增益条件,可保证原点的局部(resp.非局部)渐近稳定性(resp.紧凑集的全局吸引性)。在附加条件保证解在合适域内几乎所有初始条件收敛时,原点的几乎全局渐近稳定性得以保证。两个例子说明并激励了这一方法。

英文摘要:

A sufficient condition for the stability of a system resulting from the interconnection of dynamical systems is given by the small gain theorem. Roughly speaking, to apply this theorem, it is required that the gains composition is continuous, increasing and upper bounded by the identity function. In this work, an alternative sufficient condition is presented for the case in which this criterion fails due to either lack of continuity or the bound of the composed gain is larger than the identity function. More precisely, the local (resp. non-local) asymptotic stability of the origin (resp. global attractivity of a compact set) is ensured by a region-dependent small gain condition. Under an additional condition that implies convergence of solutions for almost all initial conditions in a suitable domain, the almost global asymptotic stability of the origin is ensured. Two examples illustrate and motivate this approach.
