[Sur une méthode d'éléments finis pour résoudre des problèmes de contrôle optimal régis par l'équation d'onde unidimensionnelle généralisée]
Cet article traite des problèmes de contrôle optimal régis par l'équation d'onde 1D avec coefficients variables, les espaces de contrôle étant, soit des fonctions mesurées , soit des mesures vectorielles . On construit des discrétisations bilinéaires des éléments finis et on en analyse la stabilité et l'erreur.
The paper deals with the optimal control problems governed by the 1D wave equation with variable coefficients and the control spaces of either measure-valued functions or vector measures . Bilinear finite element discretizations are constructed and their stability and error analysis is accomplished.
