摘要:

本文研究了由J. Bona,M. Chen和J. - C.炒这是一个理想流体表面上小振幅长波运动的模型。本文考虑有限区域上KdV-KdV型Boussinesq系统,齐次Dirichlet-Neumann边界控制作用在区间右端点.我们的目标是建立合适的积分变换以获得导致系统稳定的反馈控制律。更准确地说,我们将证明,解决方案的闭环系统的指数衰减到零的$L^2(0,L)$ -范数和衰减率可以调整到所需的大,如果初始数据是足够小的。

英文摘要:

This work deals with the local rapid exponential stabilization for a Boussinesq system of KdV-KdV type introduced by J. Bona, M. Chen and J.-C. Saut. This is a model for the motion of small amplitude long waves on the surface of an ideal fluid. Here, we will consider the Boussinesq system of KdV-KdV type posed on a finite domain, with homogeneous Dirichlet--Neumann boundary controls acting at the right end point of the interval. Our goal is to build suitable integral transformations to get a feedback control law that leads to the stabilization of the system. More precisely, we will prove that the solution of the closed-loop system decays exponentially to zero in the $L^2(0,L)$--norm and the decay rate can be tuned to be as large as desired if the initial data is small enough.
