On the Neumann Boundary Controllability for the Non-Homogeneous String on a Half-Axis

In the paper, the equation of a vibrating non-homogeneous string, whose potential is not equal to a constant, is considered on a half-axis. The Neumann control of the class L∞ is considered at a point x = 0. The control problem is studied in the Sobolev spaces. The suffcient conditions for nullcontr...

Description
Summary:In the paper, the equation of a vibrating non-homogeneous string, whose potential is not equal to a constant, is considered on a half-axis. The Neumann control of the class L∞ is considered at a point x = 0. The control problem is studied in the Sobolev spaces. The suffcient conditions for nullcontrollability and approximate null-controllability at a free time T > 0 are obtained for the given system. The controls solving these problems are found explicitly. Рассмотрено уравнение колебания неоднородной струны на полуоси с потенциалом, не равным константе. На левом конце рассмотрено управление типа Неймана из класса L∞. Задача управляемости изучена в пространствах Соболева. Для заданной системы получены достаточные условия 0-управляемости и ε-управляемости за свободное время T > 0. Управления, которые решают эти задачи, найдены в явном виде.
