Approche LMI pour la synthèse de correcteurs et d'observateurs : application aux systèmes spatiaux et bilinéaires

Abstract : The growing power and popularity of LMI rnethods for control yield to consider the control design problem as a multiobjectives optimization one. The growing evolution of aerospace activities and the flexibility of its structures require more and more constraining robustness and performance specifications. In face of this growing complexity, we turn to the use of generical LMI-based algorithms, taking into account the poor conditionning of such systems. To treat this kind of specifications, we use a mixed H2/H[infini] output feedback control for both continuous and dis crete time linear systems. To facilitate its implementation, an arder reduction of the obtained controller is then realized. This thesis work was realized under a collaboration between Matra Marconi Space and the CNES, and applied to the line sight and attitude control of a telecommunication satellite.
