A problem of boundary controllability for a plate

open access: yesEvolution Equations and Control Theory, 2013
The boundary controllability problem, here discussed, might be described by a two-dimensional space equation modeling, at the same time $t$, different physical phenomena in a composite solid made of different materials. These phenomena may be governed, at the same time $t$, for example, by the heat equation and by the Schrodinger equation in two ...

On the boundary control of a flexible robot arm [PDF]

open access: yesProceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002
We consider a flexible robot arm modeled as a single flexible link clamped to a rigid body. We assume that the system performs only planar motion. For this system, we pose two control problems; namely, the orientation and stabilization of the system. We propose a class of controllers to solve these problems.

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

open access: yesFEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

How HRM control affects boundary-spanning employees’ behavioural strategies and satisfaction : The moderating impact of cultural performance orientation [PDF]

open access: yes
This study examines how cultural performance orientation moderates the influence of human resource management (HRM) controls on boundary-spanning employees’ behavioural strategies and satisfaction.HRM control; national culture; performance orientation ...

On control laws for discrete linear repetitive processes with dynamic boundary conditions [PDF]

open access: yes, 2008
Repetitive processes are characterized by a series of sweeps, termed passes, through a set of dynamics defined over a finite duration known as the pass length.

Optimal boundary control of a nonstandard viscous Cahn-Hilliard system with dynamic boundary condition [PDF]

open access: yes, 2016
In this paper, we study an optimal boundary control problem for a model for phase separation taking place in a spatial domain that was introduced by Podio-Guidugli in Ric. Mat. 55 (2006), pp. 105-118.

Boundary control problem for the telegraph equation

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
In the paper we consider the boundary control problem for the telegraph equation. We study the case of the short period of control, when the initial and final data determine the solution in two regions, having the common part.

Approximate controllability of the coupled degenerate system with two boundary controls

open access: yesBoundary Value Problems, 2017
In this paper, we investigate the approximate controllability of the coupled system with boundary degeneracy. The control functions act on the degenerate boundary. We prove the Carleman estimate and the unique continuation of the adjoint system.

Dynamic boundary control of the timoshenko beam [PDF]

open access: yesAutomatica, 1992
Abstract We consider a clamped-free Timoshenko beam. To stabilize the beam vibrations, we propose a dynamic boundary control law applied at the free end of the beam. We prove that with the proposed control law, the beam vibrations uniformly and exponentially decay to zero. The proof uses a Lyapunov functional based on the energy of the system.
