一类耦合退化系统零能控性的代数条件

On Algebraic condition for null controllability of some coupled degenerate systems

E. M. Ait Benhassi, M. Fadili, L. Maniar

摘要:

本文将零能控性的Kalman秩条件推广到具有常系数、可对角化扩散矩阵和$m$ -控制的$n$ -耦合线性退化抛物系统。为此,我们证明了一个整体Carleman估计的解决方案的标量$2n$阶方程,然后我们从它推断出相应的伴随系统的可观测性不等式,从而零能控性。

英文摘要:

In this paper we will generalize the Kalman rank condition for the null controllability to $n$-coupled linear degenerate parabolic systems with constant coefficients, diagonalizable diffusion matrix, and $m$-controls. For that we prove a global Carleman estimate of the solution of a scalar $2n$-order equation then we infer from it an observability inequality for the corresponding adjoint system, and thus the null controllability.
