Energy decay and weak observability for some evolution systems
Kaïs Ammari, Faouzi Triki
In an abstract functional framework, we investigate the equivalence between two fundamental properties: weak observability and energy decay associated with certain classes of dissi…
Bilinear optimal stabilization of a non-homogeneous Fokker-Planck equation
K. Ammari, M. Ouzahra, S. Yahyaoui
In this work, we study the bilinear optimal stabilization of a non-homogeneous Fokker-Planck equation. We first study the problem of optimal control in a finite-time interval and t…
Feedback stabilization for a bilinear control system under weak observability inequalities
Kaïs Ammari, Mohamed Ouzahra
In this paper, we discuss the feedback stabilization of bilinear systems under weak observation properties. In this case, the uniform stability is not guaranteed. Thus we provide a…
The best decay rate of the damped plate equation in a square
Kaïs Ammari, Abdelkader Saïdi
In this paper we study the best decay rate of the solutions of a damped plate equation in a square and with a homogeneous Dirichlet boundary conditions. We show that the fastest de…
Local feedback stabilisation to a non-stationary solution for a damped non-linear wave equation
Kaïs Ammari, Thomas Duyckaerts, Armen Shirikyan
We study a damped semi-linear wave equation in a bounded domain with smooth boundary. It is proved that any sufficiently smooth solution can be stabilised locally by a finite-dimen…
