The main goal of this conference paper is to report some results concerning the solution of the Linear-Quadratic optimal control problem with partial stabilization constraint (LQPS). This problem is considered for the class of exponentially stabilizable infinite-dimensional semigroup statespace systems with bounded sensing and control, having their...

Les ressources lexicales (dictionnaires, bases de données, thesaurus, etc.) rassemblent des connaissances sur les mots, leurs sens et leurs usages. Si pendant des siècles elles ont été tributaires de l'imprimerie et du format textuel, il existe de nos jours une grande variété d'outils et de ressources accessibles sous des formats électroniques dive...

The Linear-Quadratic optimal control problem with a partial stabilization constraint (LQPS) is considered for exponentially stabilizable infinite dimensional semigroup state-space systems with bounded sensing and control (having their transfer function with entries in the algebra \mathop BÙ \mathop \mathcal{B}\limits^ \wedge . It is reported that...

The linear-quadratic optimal control problem with a partial stabilization constraint is considered for a simple model of perturbed heat diffusion in a finite rod with approximate point control and observation of the temperature

This paper reports the solution of the Linear-Quadratic optimal control problem with partial stabilization constraint (LQPS) for the class of exponentially stabilizable infinite-dimensional semigroup state-space systems with bounded sensing and control having their transfer functions with entries in the algebra , (Callier and Desoer, 1978 and 1980)...

The nonnegative self-adjoint solutions of the operator Riccati equation (ORE) are studied for stabilizable semigroup Hilbert state space systems with bounded sensing and control. Basic properties of the maximal solution of the ORE are investigated: stability of the corresponding closed loop system, structure of the kernel, Hilbert-Schmidt property....

This paper presents a method for the automatic generation of aligned bilingual corpora in a Web-based reading tool for Dutch texts by French speaking learners (NEDERLEX). The authors first discuss the major functions of NEDERLEX. Then they describe the role of bilingual corpora in the design and construction of the NEDERLEX tool, as well as the app...
