Quadratures of Pontryagin extremals for optimal control problems [PDF]

open access: yes, 2006
We obtain a method to compute effective first integrals by combining Noether's principle with the Kozlov-Kolesnikov integrability theorem. A sufficient condition for the integrability by quadratures of optimal control problems with controls taking values

Orbital Impulsive Pursuit–Evasion Game in the Cislunar Space

open access: yesAerospace
A pursuer and an evader can exploit low-energy, non-Keplerian trajectories in cislunar space, making it difficult to obtain the saddle point for impulsive orbital pursuit–evasion games (OPEG).

Navigating the Professional Journey for Adults with Attention Deficit/Hyperactivity Disorder: Challenges and Strategies

open access: yesEuropean Psychiatry
Introduction Attention deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects approximately 5% of adults. Individuals with ADHD often display symptoms of inattention, including poor time management and difficulty ...

Second order necessary conditions of optimality for impulsive control problems

open access: yes2001 European Control Conference (ECC), 2001
In this article, we present first and second order conditions for an impulsive optimal control problem. Although far from being the most general one to which the adopted approach can be applied, it is sufficiently rich to illustrate the power of our methods. After a detailed description of the considered impulsive optimal control problem, the first and

The Deterministic Impulse Control Maximum Principle in Operations Research: Necessary and Sufficient Optimality Conditions (replaces CentER DP 2011-052) [PDF]

open access: yes
This paper considers a class of optimal control problems that allows jumps in the state variable. We present the necessary optimality conditions of the Impulse Control Maximum Principle based on the current value formulation.

OPTIMAL IMPULSIVE CONTROL FOR TIME DELAY SYSTEMS [PDF]

open access: yes
We introduce discontinuous solutions to nonlinear impulsive control systems with state time delays in the dynamics and derive necessary optimality conditions in the form of a max- imum principle for associated optimal control problems.

Second Order Necessary Conditions for Optimal Impulsive Control Problems

open access: yesJournal of Dynamical and Control Systems, 2003
The authors have derived first- and second-order necessary conditions for optimality for an impulsive control problem. These conditions are proved by decoding the conditions obtained by applying the extremal principle for an abstract problem. Two examples illustrating the main features of these conditions are given.

Optimal Partial Harvesting Schedule for Aquaculture Operations [PDF]

open access: yes
When growth is density dependent, partial harvest of the standing stock of cultured species (fish or shrimp) over the course of the growing season (i.e., partial harvesting) would decrease competition and thereby increase individual growth rates and ...
