On the Existence of Optimal Controls for SPDEs with Boundary Noise and Boundary Control [PDF]

SIAM Journal on Control and Optimization, 2013
We consider a stochastic optimal control problem for an heat equation with boundary noise and boundary controls. Under suitable assumptions on the coefficients, we prove existence of optimal controls in strong sense by solving the stochastic hamiltonian system related.

On boundary stimulation and optimal boundary control of the bidomain equations. [PDF]

Math Biosci, 2013
The bidomain equations with Neumann boundary stimulation and optimal control of these stimuli are investigated. First an analytical framework for boundary control is provided. Then a parallel finite element based algorithm is devised and its efficiency is demonstrated not only for the direct problem but also for the optimal control problem.

Nonlinear control of unsteady finite-amplitude perturbations in the Blasius boundary-layer flow [PDF]

, 2013
The present work provides an optimal control strategy, based on the nonlinear Navier–Stokes equations, aimed at hampering the rapid growth of unsteady finite-amplitude perturbations in a Blasius boundary-layer flow.

Optimal control of a stochastic heat equation with boundary-noise and boundary-control [PDF]

ESAIM: Control, Optimisation and Calculus of Variations, 2007
The authors of the present paper study a controlled state equation of parabolic type with Neumann boundary condition over the interval \([0,\pi]\). In the boundary condition at \(0\) and at \(\pi\) the derivative of the solution equals to the sum of a control and of a white noise in time; the two white noises intervening at the both interval end points

Stability and Stabilization of a Class of Boundary Control Systems [PDF]

, 2005
We study a class of partial differential equations on a one dimensional spatial domain with control and observation at the boundary. For this class of systems we describe how to obtain an impedance energy-preserving system, as well as scattering energy ...

Boundary control for transport equations

Mathematical Control and Related Fields, 2023
This paper considers two types of boundary control problems for linear transport equations. The first one shows that transport solutions on a subdomain of a domain X can be controlled exactly from incoming boundary conditions for X under appropriate convexity assumptions.

On a class of boundary control problems [PDF]

Operators and Matrices, 2014
We discuss a class of linear control problems in a Hilbert space setting, which covers diverse systems such as hyperbolic and parabolic equations with boundary control and boundary observation even including memory terms. We introduce abstract boundary data spaces in which the control and observation equations can be formulated without strong geometric
