Title: Finite-Time Stabilization of a Class of Nonlinear Systems in Hilbert Space

Title: 有限时间区间内希尔伯特空间中一类非线性系统的稳定化

Authors:Kamal Fenza, Moussa Labbadi, Mohamed Ouzahra
Abstract: This paper deals with the finite-time stabilization of a class of nonlinear infinite-dimensional systems. First, we consider a bounded matched perturbation in its linear form. It is shown that by using a set-valued function, both the convergence objective (finite-time) and the rejection of perturbations are achieved. Second, we consider a class of nonlinear systems and design a feedback control that ensures the closed-loop system is finite-time stable. All proofs presented in this paper regarding convergence are based on Lyapunov theory. The existence of solutions to the closed-loop system and its well-posedness are established using maximal monotone theory. To illustrate the applicability of the theoretical results, a heat equation is considered as an application of the main results.
Abstract: 本文研究一类非线性无限维系统的有限时间稳定性问题。 首先,我们考虑其线性形式中的有界匹配扰动。 结果表明,通过使用一个集值函数,既实现了收敛目标(有限时间),又实现了扰动的抑制。 其次,我们考虑一类非线性系统,并设计一种反馈控制,确保闭环系统是有限时间稳定的。 本文中所有关于收敛性的证明均基于李雅普诺夫理论。 利用最大单调理论建立了闭环系统的解的存在性和适定性。 为了说明理论结果的适用性,将热方程作为主要结果的一个应用实例进行考虑。
