On approximate and exact null controllability of delay systems [PDF]

open access: yesSystems & Control Letters, 1984
Approximate and exact null controllability of linear delay equations with a constant delay and scalar control are shown to be equivalent. The main tool is a recent result on equivalence between spectral controllability and finite spectrum assignability.

Exact null controllability of semilinear integrodifferential systems in Hilbert spaces

open access: yesJournal of Mathematical Analysis and Applications, 2004
The authors remove the bounded invertibility condition replacing it by the exact null controllability of the associated linear system with additive term. Exact null controllability of this system does not guarantee the boundedness of \((L_0)^{-1}\), but it guarantees the boundedness of the operator \((L_0)^{-1}N^T_0\) which is defined in Lemma 3.

Exact null-controllability of interconnected abstract evolution equations with unbounded input operators

open access: yesDiscrete & Continuous Dynamical Systems, 2021
The exact null-controllability problem in the class of smooth controls with applications to interconnected systems was considered in [23] for the case of bounded input operators appearing in systems with distributed controls.

Null-controllability, exact controllability, and stabilization of hyperbolic systems for the optimal time [PDF]

open access: yes2020 59th IEEE Conference on Decision and Control (CDC), 2020
In this paper, we discuss our recent works on the null-controllability, the exact controllability, and the stabilization of linear hyperbolic systems in one dimensional space using boundary controls on one side for the optimal time.

Optimization of non-cylindrical domains for the exact null controllability of the 1D wave equation [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2021
This work is concerned with the null controllability of the one-dimensional wave equation over non-cylindrical distributed domains. The controllability in that case has been obtained by Castro et al. [SIAM J. Control Optim.

Exact boundary null controllability for a coupled system of plate equations with variable coefficients

open access: yesEvolution Equations and Control Theory, 2021
This paper studies a coupled system of plate equations with variable coefficients, subject to the clamped boundary conditions. By the Riemannian geometry approach, the duality method, the multiplier technique and a compact perturbation method, we ...
