چکیده

In this report, we state and prove rstand second-order necessary conditions in Pontryagin form for optimal control problems with pure state and mixed control-state constraints. We say that a Lagrange multiplier of an optimal control problem is a Pontryagin multiplier if it is such that Pontryagin's minimum principle holds, and we call optimality conditions in Pontryagin form those which only involve Pontryagin multipliers. Our conditions rely on a technique of partial relaxation, and apply to Pontryagin local minima. Key-words: Optimal control; pure state and mixed control-state constraints; Pontryagin's principle; Pontryagin multipliers; second-order necessary conditions; partial relaxation. The research leading to these results has received funding from the EU 7th Framework Programme (FP7PEOPLE-2010-ITN), under GA number 264735-SADCO, and from the Gaspard Monge Program for Optimization and operations research (PGMO). ∗ Inria-Saclay and CMAP, Ecole Polytechnique, Route de Saclay, 91128 Palaiseau Cedex, France.

Nous appelons multiplicateur de Pontryaguine tout multiplicateur de Lagrange pour lequel le principe de Pontryaguine est satisfait et parlons de conditions d'optimalité sous forme Pontryaguine si elles ne font intervenir que des multiplicateurs de Pontryaguine. Nos conditions s'appuient sur une technique de relaxation partielle et sont valables pour des minima de Pontryaguine.

Second order conditions in optimal control problems with mixed equality - type constraints on a variable time interval

Abstract: This paper provides an analysis of second-order necessary or sufficient optimality conditions of Pontryagin or bounded strong minima, for optimal control problems of ordinary differential equations, considered on a nonfixed time interval, with constraints on initial-final time-state as well as mixed state-control constraints of equality type satisfying condition of linear independence...

The Pontryagin Maximum Principle and Transversality Conditions for a Class of Optimal Control Problems with Infinite Time Horizons

This paper suggests some further developments in the theory of first-order necessary optimality conditions for problems of optimal control with infinite time horizons. We describe an approximation technique involving auxiliary finite-horizon optimal control problems and use it to prove new versions of the Pontryagin maximum principle. Special attention is paid to the behavior of the adjoint var...

Lipschitzian Regularity of the Minimizing Trajectories for Nonlinear Optimal Control Problems

We consider the Lagrange problem of optimal control with unrestricted controls and address the question: under what conditions we can assure optimal controls are bounded? This question is related to the one of Lipschitzian regularity of optimal trajectories, and the answer to it is crucial for closing the gap between the conditions arising in the existence theory and necessary optimality condit...

Pontryagin Maximum Principle for Optimal Control of

In this paper we investigate optimal control problems governed by variational inequalities. We present a method for deriving optimality conditions in the form of Pontryagin's principle. The main tools used are the Ekeland's variational principle combined with penalization and spike variation techniques. 1. Introduction. The purpose of this paper is to present a method for deriving a Pontryagin ...

Necessary and sufficient conditions for optimal controls in viscous flow problems

Optimal control theory of viscous flow has several applications in engineering science. In [20], a fundamental optimal control problem in exterior hydrodynamics was studied. In that paper, the task of accelerating an obstacle from rest to a given speed in a given time, minimising the energy expenditure, was considered. In [13] a unified formulation of optimal control problems in viscous hydrody...
