一类非线性ODE-PDE系统的适定性与鲁棒稳定性

Well-posedness and robust stability of a nonlinear ODE-PDE system

S. Dashkovskiy, O. Kapustyan, V. Slynko

摘要:

本文研究了一类由常微分方程和抛物型偏微分方程组成的非线性系统在外部扰动通过抛物型方程边界条件进入时的稳定性和鲁棒性。为此,我们开发了一个合适的强制性李雅普诺夫函数作为主要结果之一的建设方法。基于此李雅普诺夫函数,我们建立所考虑的系统的适定性,并建立条件,保证ISS属性。ISS估计推导出明确的全球Lipschitz非线性的特定情况下。

英文摘要:

This work studies stability and robustness of a nonlinear system given as an interconnection of an ODE and a parabolic PDE subjected to external disturbances entering through the boundary conditions of the parabolic equation. To this end we develop an approach for a construction of a suitable coercive Lyapunov function as one of the main results. Based on this Lyapunov function we establish the well-posedness of the considered system and establish conditions that guarantee the ISS property. ISS estimates are derived explicitly for the particular case of globally Lipschitz nonlinearities.
