Contents The problem of observer design naturally arises in a system approach, as soon as
one needs some internal information from external (directly available) measurements. In …

In this paper, control theory is used to formalize finite-time chaos synchronization as a
nonlinear finite-time observer design issue. This paper introduces a finite-time observer for …

Elimination of unknowns in a system of differential equations is often required when
analyzing (possibly nonlinear) dynamical systems models, where only a subset of variables …

A global finite-time observer is designed for nonlinear systems which are uniformly
observable and globally Lipschitz. This result is based on a high-gain approach combined …

The problem of the immersion of a SISO system into a linear up to an output injection one is
studied in order to design Luenberger-like observers. Necessary and sufficient conditions …

The problem under interest is the linearization of nonlinear MIMO systems by generalized
input-output injection in order to design observers with linear error dynamics. The method is …

This paper addresses the design of discrete-time nonlinear observers through the circle
criterion. The new design method is mainly devoted to either globally Lipschitz systems or …

This paper deals with the design of unknown input observers for nonlinear systems. An
algorithm which determines if the state and the unknown input of the system can be …

To handle the state estimation of a nonlinear system perturbed by a scalar disturbance
distributed by a known nonlinear vector, we incorporate a sliding mode term into a nonlinear …

In recent years, the availability of computer-based methods has created a revival of interests
in exploring algebraic methods in nonlinear context. This paper proposes a new approach to …
