摘要:

我们提出了一种具有动态供给率的非线性系统耗散性的一般概念。这扩展了具有静态供给率以及各种二次型动态供给率的经典耗散性。本文的主要结果涉及非线性反馈耗散系统的 Lyapunov 和渐近稳定性分析,这些系统由相对于相容动态供给率的耗散不等式表征,但涉及可能不同且独立的辅助系统。重要的是,我们提供了保证反馈系统状态稳定性的耗散性条件,而无需考虑辅助系统状态的稳定性。关键结果也专门用于由动态 (Psi, Pi, Upsilon, Omega)-耗散性描述的两个非线性系统互连的简单耦合测试,并表明能够恢复文献中的若干现有结果,包括小增益、无源性指标、静态 (Q, S, R)-耗散性、具有终端代价的耗散性等。我们还与基于积分二次约束的反馈稳定性分析的输入-输出方法进行了比较。

英文摘要:

We propose a general notion of dissipativity with dynamic supply rates for nonlinear systems. This extends classical dissipativity with static supply rates and dynamic supply rates of miscellaneous quadratic forms. The main results of this paper concern Lyapunov and asymptotic stability analysis for nonlinear feedback dissipative systems that are characterised by dissipation inequalities with respect to compatible dynamic supply rates but involving possibly different and independent auxiliary systems. Importantly, dissipativity conditions guaranteeing stability of the state of the feedback systems, without concerns on the stability of the state of the auxiliary systems, are provided. The key results also specialise to a simple coupling test for the interconnection of two nonlinear systems described by dynamic (Psi, Pi, Upsilon, Omega)-dissipativity, and are shown to recover several existing results in the literature, including small-gain, passivity indices, static (Q, S, R)-dissipativity, dissipativity with terminal costs, etc. Comparison with the input-output approach to feedback stability analysis based on integral quadratic constraints is also made.
