Contribution sur la synthèse d'observateurs pour les systèmes dynamiques hybrides

Abstract : The thesis is concerned with the observers synthesis for the hybrid dynamic systems. We particularly consider
the systems described by a finite set of discrete-time linear subsystems and a commutation law. The active subsystem and the
commutations between the subsystems can be defined by a controllable external command (switched systems), or by the
autonomous transitions (piecewise affine linear systems). Under the assumption of the knowledge of the active mode, we show that
the association of the switched observer with a pole placement constraint allows to propose observation scheme to solve the
synchronization problem of the switched chaotic systems with an embedded message. In the case of piecewise affine systems, we
propose a method to detect the active mode. The association of this method with the switched observer allows the joint estimate
of the continuous state and discrete state. Finally, we consider the case of commutations governed by a PN. We propose an
observation scheme using a PN observer and a switched observer.
