Le but de ce livre est de presenter les developpements recents du controle geometrique oriente vers la commande des vehicules spatiaux. Son contenu a servi de base a une serie de cours de controle et d'automatique de 3e cycle. Il s'appuie sur des projets de recherche avec l'ESTEC et le CNES, sur le controle d'attitude d'un satellite, le probleme de transfert orbital en temps minimal, et le probleme de rentree atmospherique d'une navette spatiale.

This book presents recent advances in space and celestial mechanics, with a focus on the N-body problem and astrodynamics, and explores the development and application of computational techniques in both areas. It highlights the design of space transfers with various modes of propulsion, like solar sailing and low-thrust transfers between libration point orbits, as well as a broad range of targets and applications, like rendezvous with near Earth objects. Additionally, it includes contributions on the non-integrability properties of the collinear three- and four-body problem, and on general...

Analyses the role of singular trajectories in control theory, containing about 60 exercises and problems. This book looks at the applications of singular trajectories to the optimisation of batch reactors. The theoretical part based on the Martinet case concerns the singularity analysis of singular trajectories in sub-Riemannian geometry.
