Optimal boundary control in a micromixer

open access: yesExamples and Counterexamples
This work studies mathematical foundations for optimal boundary control of mixers which mix two fluid phases. Existence of optima is proved and the influence of common objective functionals is discussed.

Optimal boundary control for hyperdiffusion equation [PDF]

open access: yesKybernetika, 2010
Summary: We consider the solution of optimal control problem for hyperdiffusion equation involving a boundary function of continuous time variable in its cost function. A specific direct approach based on infinite series of Fourier expansion in space and temporal integration by parts for analytical solution is proposed to solve optimal boundary control

Homogenization of boundary optimal control problem

open access: yesElectronic Journal of Differential Equations, 2022
In this article, we study the asymptotic behavior of solutions to some optimal control problems, governed by an elliptic boundary value problem with Robin boundary conditions in a periodically perforated domain. The coefficients of the differential operator in the state equation and in the cost-functional are rapidly oscillating.

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

open access: yesSIAM 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]

open access: yesMath 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.

A Boundary Optimal Control Identification Problem

open access: yes, 2020
Optimal control methods are applied in various problems and can be efficient also for solving inverse problems, such as parameter identification and boundary control which arise in many important applications. For boundary optimal control methods one can identify conditions on an inaccessible part of the boundary by letting them play the role of a ...

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

open access: yesESAIM: 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

Boundary conditions optimal control [PDF]

open access: yesThe Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1989
AbstractA simple rigorous approach is given to finding boundary conditions for the adjoint differential equation in an optimal control problem. The boundary conditions for a time-optimal problem are calculated from the simpler conditions for a fixed-time problem.

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

open access: yes, 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 boundary control problems for a hierarchical age-structured two-species model

open access: yesJournal of Inequalities and Applications, 2022
This paper discusses the optimal control problems for a nonlinear age-structured two-species model, where elder individuals are more competitive than younger ones, and each species is described by a nonlinear integropartial differential equation with a ...
