一维齐次拟线性双曲型方程组在最优时刻的稳定性

Finite-time stabilization in optimal time of homogeneous quasilinear hyperbolic systems in one dimensional space

Jean-Michel Coron, Hoai-Minh Nguyen

摘要:

研究了一类齐次拟线性双曲型方程组的有限时间镇定问题。我们提出了时间无关的反馈导致有限时间稳定的任何时间大于零可控性的线性化系统的最佳时间,如果初始条件是足够小的。其关键技术之一是建立具有非线性、非局部边界条件的拟线性双曲方程组的局部适定性。

英文摘要:

We consider the finite-time stabilization of homogeneous quasilinear hyperbolic systems with one side controls and with nonlinear boundary condition at the other side. We present time-independent feedbacks leading to the finite-time stabilization in any time larger than the optimal time for the null controllability of the linearized system if the initial condition is sufficiently small. One of the key technical points is to establish the local well-posedness of quasilinear hyperbolic systems with nonlinear, non-local boundary conditions.
