Impulsive fixed-time observer for linear time-delay systems

International audienceThis paper presents a fixed-time observer for a general class of linear time-delay systems. In contrast to many existing observers, which normally estimate system's tra-jectory in an asymptotic fashion, the proposed observer estimates system's state in a prescribed time. The proposed fixed-time observer is realized by updating the observer in an impulsive manner. Simulation results are also presented to illustrate the convergence behavior of the proposed fixed-time observer

Finite-time-observer design for nonlinear impulsive systems with impact perturbation

International audienceThis paper investigates the observer design problem of nonlinear impulsive systems with impact perturbation. By using the concept of normal form, this paper proposes a full order finite time observer, which guarantees the finite time convergence independent of the impact perturbation. Reduced order observer is additionally developed for the proposed normal form. An illustrative example is given in order to illustrate the capability of the proposed method
