On an Optimal -Control Problem in Coefficients for Linear Elliptic Variational Inequality

open access: yesAbstract and Applied Analysis, 2013
We consider optimal control problems for linear degenerate elliptic variational inequalities with homogeneous Dirichlet boundary conditions. We take the matrix-valued coefficients in the main part of the elliptic operator as controls in .

SHAPE STABILITY OF OPTIMAL CONTROL PROBLEMS IN COEFFICIENTS FOR COUPLED SYSTEM OF HAMMERSTEIN TYPE

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2014
In this paper we consider an optimal control problem (OCP) for the coupledsystem of a nonlinear monotone Dirichlet problem with matrix-valued L∞(Ω;RN×N)-controls in coecients and a nonlinear equation of Hammerstein type, where solution nonlinearly ...

A global maximum principle for optimal control of general mean-field forward-backward stochastic systems with jumps

open access: yes, 2019
In this paper we prove a necessary condition of the optimal control problem for a class of general mean-field forward-backward stochastic systems with jumps in the case where the diffusion coefficients depend on control, the control set does not need to ...

Gaussian process model based predictive control [PDF]

open access: yes, 2003
Gaussian process models provide a probabilistic non-parametric modelling approach for black-box identification of non-linear dynamic systems. The Gaussian processes can highlight areas of the input space where prediction quality is poor, due to the lack ...

Synthesis of Control and State Observer for Weakly Nonlinear Systems Based on the Pseudo-Linearization Technique

open access: yesМоделирование и анализ информационных систем, 2017
In this paper, an approach to the construction of nonlinear output tracking control on a finite time interval for a class of weakly nonlinear systems with state-dependent coefficients is considered.

Neutronic analysis of control rod effect on safety parameters in Tehran Research Reactor

open access: yesNuclear Engineering and Technology, 2018
The measurement and calculation of neutronic parameters in nuclear research reactors has an important influence on control and safety of the nuclear reactor. The power peaking factors, reactivity coefficients and kinetic parameters are the most important

Approximation of an Optimal BV -Control Problem in the Coefficient for the p(x)-Laplace Equation

open access: yesJournal of Optimization, Differential Equations and Their Applications
We study a Dirichlet optimal control problem for a quasilinear monotone elliptic equation with the so-called weighted p(x)-Laplace operator. The coefficient of the p(x)-Laplacian, the weight u, we take as a control in BV (Ω) ∩ L∞(Ω).

Nonlinear H ∞ optimal control scheme for an underwater vehicle with regional function formulation [PDF]

open access: yes, 2013
A conventional region control technique cannot meet the demands for an accurate tracking performance in view of its inability to accommodate highly nonlinear system dynamics, imprecise hydrodynamic coefficients, and external disturbances.
