摘要:

本文研究了一类对角无限维边界控制系统的边界反馈稳定问题。在所研究的设定中,边界控制输入受到恒定延迟的影响,而开环系统可能具有有限个不稳定模态。所提出的控制设计策略包括两个主要步骤。首先,通过模态分解截断原无限维系统(IDS)以获得有限维子系统,该子系统包含无限维系统的不稳定成分,并利用Artstein变换和极点移位定理设计有限维延迟控制器。其次,通过选择适当的Lyapunov函数证明:1)有限维延迟控制器成功稳定原无限维系统;2)闭环系统对分布式扰动呈指数输入-状态稳定(ISS)。最后,利用获得的ISS性质推导出一个小型增益条件,以确保IDS-ODE互联的稳定性。

英文摘要:

This paper studies the boundary feedback stabilization of a class of diagonal infinite-dimensional boundary control systems. In the studied setting, the boundary control input is subject to a constant delay while the open loop system might exhibit a finite number of unstable modes. The proposed control design strategy consists in two main steps. First, a finite-dimensional subsystem is obtained by truncation of the original Infinite-Dimensional System (IDS) via modal decomposition. It includes the unstable components of the infinite-dimensional system and allows the design of a finite-dimensional delay controller by means of the Artstein transformation and the pole-shifting theorem. Second, it is shown via the selection of an adequate Lyapunov function that 1) the finite-dimensional delay controller successfully stabilizes the original infinite-dimensional system; 2) the closed-loop system is exponentially Input-to-State Stable (ISS) with respect to distributed disturbances. Finally, the obtained ISS property is used to derive a small gain condition ensuring the stability of an IDS-ODE interconnection.
