具有非线性动态反馈系统的Euler-Bernoulli梁的稳定性

Stability of an Euler-Bernoulli beam with a nonlinear dynamic feedback system

Maja Miletić, Dominik Stürzer, Anton Arnold, Andreas Kugi

摘要:

本文研究了一个无损耗的Euler-Bernoulli梁的稳定性分析,该梁带有一个与非线性动态反馈系统耦合的末端载荷。该设置包括满足非线性KYP引理的非线性动态边界控制器以及与非线性被动环境的相互作用。严格证明了闭环PDE-ODE系统的时间整体适定性和渐近稳定性。分析是基于相应的一阶发展问题的半群理论。对于大的时间分析,预紧性的轨迹是通过推导统一的时间界限的解决方案和它的时间导数。

英文摘要:

This paper is concerned with the stability analysis of a lossless Euler-Bernoulli beam that carries a tip payload which is coupled to a nonlinear dynamic feedback system. This setup comprises nonlinear dynamic boundary controllers satisfying the nonlinear KYP lemma as well as the interaction with a nonlinear passive environment. Global-in-time wellposedness and asymptotic stability is rigorously proven for the resulting closed-loop PDE-ODE system. The analysis is based on semigroup theory for the corresponding first order evolution problem. For the large-time analysis, precompactness of the trajectories is shown by deriving uniform-in-time bounds on the solution and its time derivatives.
