Necessity and sufficiency conditions for the absolute null controllability for Linear delay perturbations

Abstract

We are inspired by the works of Chukwu [1], Eke [2], Schinterdorf and Barmish [4] to unveil necessary and sufficient conditions for the absolute null controllability of a linear delay perturbed system with zero in the domain of null controllability.
