具有非线性动态边界条件的Wave Equation的速度镇定

Velocity Stabilization of a Wave Equation with a Nonlinear Dynamic Boundary Condition

Nicolas Vanspranghe, Francesco Ferrante, Christophe Prieur

摘要:

本文讨论了一维波动方程的非线性动力边界条件和作用于另一端的Neumann型边界控制。我们考虑一类仅依赖于控制端速度的非线性镇定反馈。不受控边界服从非线性一阶项,其可以表示非线性边界反阻尼。在与问题相关联的最优能量空间中获取初始数据。在不同的情况下,机械能的指数衰减进行了研究。建立了合适不变集的稳定性和吸引性。

英文摘要:

This paper deals with a one-dimensional wave equation with a nonlinear dynamic boundary condition and a Neumann-type boundary control acting on the other extremity. We consider a class of nonlinear stabilizing feedbacks that only depend on the velocity at the controlled extremity. The uncontrolled boundary is subject to a nonlinear first-order term, which may represent nonlinear boundary anti-damping. Initial data is taken in the optimal energy space associated with the problem. Exponential decay of the mechanical energy is investigated in different cases. Stability and attractivity of suitable invariant sets are established.
