Optimal Control for the Thermistor Problem [PDF]

SIAM Journal on Control and Optimization, 2010
This paper is concerned with the state-constrained optimal control of the two-dimensional thermistor problem, a quasi-linear coupled system of a parabolic and elliptic PDE with mixed boundary conditions. This system models the heating of a conducting material by means of direct current.

Optimal fluctuations and the control of chaos. [PDF]

, 2002
The energy-optimal migration of a chaotic oscillator from one attractor to another coexisting attractor is investigated via an analogy between the Hamiltonian theory of fluctuations and Hamiltonian formulation of the control problem.

ON OPTIMALITY OF SINGULAR CONTROLS IN AN OPTIMAL CONTROL PROBLEM [PDF]

Vestnik Tomskogo gosudarstvennogo universiteta. Matematika i mekhanika, 2016
Summary: In this paper, a Moskalenko type optimal control problem is considered. We consider the optimal control problem of minimizing the terminal type functional \[\text{S(u,v)}=\varphi(y(x_1))+\int_{x_0}^{x_1}G(x,z(t_1,x))\,dx,\] under constraints \[ u(t,x)\in U\subset R^r, \quad (t,x)\in D=[t_0,t_1]\times[x_0,x_1], \] \[ v(x)\in V\subset R^q,\quad ...

An optimal gains matrix for time-delay feedback control [PDF]

, 2009
In this paper we propose an optimal time-delayed feedback control (TDFC) for tracking unstable periodic orbits (UPOs). It is shown that TDFC will drive a trajectory onto a periodic orbit while minimising an integral of a cost function of the error in ...

Optimization problems in congestion control [PDF]

Proceedings 41st Annual Symposium on Foundations of Computer Science, 2002
One of the crucial elements in the Internet's success is its ability to adequately control congestion. The paper defines and solves several optimization problems related to Internet congestion control, as a step toward understanding the virtues of the TCP congestion control algorithm currently used and comparing it with alternative algorithms. We focus

A method for optimal control problems [PDF]

Revue Africaine de Recherche en Informatique et Mathématiques Appliquées, 2006
We deal with a numerical method for HJB equations coming from optimal control problems with state constraints. More precisely, we present here an antidissipative scheme applied on an adaptative grid. The adaptative grid is generated using linear quadtree structure.

Disease control as an optimization problem [PDF]

PLOS ONE, 2020
Traditionally, expert epidemiologists devise policies for disease control through a mixture of intuition and brute force. Namely, they use their know-how to narrow down the set of logically conceivable policies to a small family described by a few parameters, following which they conduct a grid search to identify the optimal policy ...

Optimal kinematic control of an autonomous underwater vehicle [PDF]

, 2009
This note investigates the motion control of an autonomous underwater vehicle (AUV). The AUV is modeled as a nonholonomic system as any lateral motion of a conventional, slender AUV is quickly damped out. The problem is formulated as an optimal kinematic

Optimal periodic output feedback control: a continuous-time approach [PDF]

, 2007
: This paper addresses the problem of optimal static output feedback control of linear periodic systems. The proposed approach, which allows to deal with both stable and unstable open loop systems, relies on a continuous-time formulation of the control ...

Optimal Reinsurance Problem under Fixed Cost and Exponential Preferences

Mathematics, 2021
We investigate an optimal reinsurance problem for an insurance company taking into account subscription costs: that is, a constant fixed cost is paid when the reinsurance contract is signed.
