Controllability and null controllability of linear systems

open access: yesJournal of Applied Sciences and Environmental Management, 2006
This paper establishes sufficient conditions for the controllability and null controllability of linear systems. The aim is to use the variation of constant formula to deduce our controllability grammiam, by exploiting the properties of the grammiam and ...

Null controllability of a thermoelastic plate

open access: yesAbstract and Applied Analysis, 2002
Thermoelastic plate model with a control term in the thermal equation is considered. The main result in this paper is that with thermal control, locally distributed within the interior and square integrable in time and space, any finite energy solution can be driven to zero at the control time T.

A Best Cost of Null Controllability for the 1D Heat Equation by Strategic Zone Profile

open access: yesJournal of Mathematics, 2021
This study is the third step of a project on the null controllability of the 1D heat equation. First, we show a boundary and internal results of controllability by a new approach using a linear, continuous, and surjective operator built from the solution

Null-control and measurable sets [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2012
We prove the interior and boundary null-controllability of some parabolic evolutions with controls acting over measurable sets.

Null controllability for a singular heat equation with a memory term

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
In this paper we focus on the null controllability problem for the heat equation with the so-called inverse square potential and a memory term. To this aim, we first establish the null controllability for a nonhomogeneous singular heat equation by a new ...
