Approximate Controllability of Second-Grade Fluids [PDF]

open access: yesJournal of Dynamical and Control Systems, 2020
This paper deals with the controllability of the second grade fluids, a class of non-Newtonian of differentiel type, on a two-dimensional torus. Using the method of Agrachev-Sarychev [1], [2] and of Sirikyan [26], we prove that the system of second grade fluids is approximately controllable by a finite-dimensional control force.

Controllability of spin-boson systems [PDF]

open access: yes, 2015
In this paper we study the so-called spin-boson system, namely {a two-level system} in interaction with a distinguished mode of a quantized bosonic field. We give a brief description of the controlled Rabi and Jaynes--Cummings models and we discuss their

Some controllability results for linear viscoelastic fluids [PDF]

open access: yes, 2012
We analyze the controllability properties of systems which provide a description, at first approximation, of a kind of viscoelastic fluid. We consider linear Maxwell fluids.

Null controllability of a semilinear degenerate parabolic equation with a gradient term

open access: yesBoundary Value Problems, 2020
This paper concerns the null controllability of a semilinear control system governed by degenerate parabolic equation with a gradient term, where the nonlinearity of the problem is involved with the first derivative. We first establish the well-posedness

Approximate controllability and lack of controllability to zero of the heat equation with memory [PDF]

open access: yes, 2014
In this paper we consider the heat equation with memory in a bounded region $\Omega \subset\mathbb{R}^d$, $d\geq 1$, in the case that the propagation speed of the signal is infinite (i.e. the Colemann-Gurtin model).

Optimal control of the propagation of a graph in inhomogeneous media [PDF]

open access: yes, 2009
We study an optimal control problem for viscosity solutions of a Hamilton–Jacobi equation describing the propagation of a one-dimensional graph with the control being the speed function.
