基于时变反馈律的一类Korteweg-de Vries方程的局部指数镇定

Local exponential stabilization for a class of Korteweg-de Vries equations by means of time-varying feedback laws

Jean-Michel Coron, Ivonne Rivas, Shengquan Xiang

摘要:

研究了一类非线性Korteweg-de Vries方程在线性化后的控制系统不可控的情况下的指数镇定问题。该系统在区间的端点处具有Dirichlet边界条件,在作为控制的右端点处具有Neumann非齐次边界条件。建立了一类时变反馈律,使得闭环系统的解在小初始值时指数衰减到0。我们还提出了一般的时变反馈律的闭环系统的适定性的结果。

英文摘要:

We study the exponential stabilization problem for a nonlinear Korteweg-de Vries equa- tion on bounded interval in cases where the linearized control system is not controllable. The system has Dirichlet boundary conditions at the end-points of the interval, a Neumann nonhomogeneous boundary condition at the right end-point which is the control. We build a class of time-varying feedback laws for which the solutions of the closed-loop systems with small initial data decay exponentially to 0. We present also results on the well-posedness of the closed-loop systems for general time-varying feedback laws.
