一类非完美界面问题的精确内能控性

Exact Internal Controllability for a Problem with Imperfect Interface

S. Monsurrò, A. K. Nandakumaran, C. Perugia

摘要:

本文研究了定义在两分量区域上的二阶线性发展方程的内部精确能控性。在界面上,我们规定解的跳跃与余法向导数成正比,同时在外边界上施加齐次Dirichlet条件。由于域的几何形状,我们应用控制通过两个区域,这是一部分的外部边界和整个接口的邻域,分别。我们的方法,内部精确可控性包括在证明一个可观性不等式,使用拉格朗日乘子方法。最后,我们应用希尔伯特唯一性方法,介绍了J。L.狮子,这导致建设的确切控制通过解决伴随问题。最后,我们找到了一个下界的控制时间不仅取决于我们的域的几何形状和我们的问题的系数系数矩阵,但也对系数的比例跳跃的余法向导数。

英文摘要:

In this paper we study the internal exact controllability for a second order linear evolution equation defined in a two-component domain. On the interface we prescribe a jump of the solution proportional to the conormal derivatives, meanwhile a homogeneous Dirichlet condition is imposed on the exterior boundary. Due to the geometry of the domain, we apply controls through two regions which are neighborhoods of a part of the external boundary and of the whole interface, respectively. Our approach to internal exact controllability consists in proving an observability inequality by using the Lagrange multipliers method. Eventually we apply the Hilbert Uniqueness Method, introduced by J.-L. Lions, which leads to the construction of the exact control through the solution of an adjoint problem. Finally we find a lower bound for the control time depending not only on the geometry of our domain and on the matrix of coefficients of our problem but also on the coefficient of proportionality of the jump with respect to the conormal derivatives.
