This article proposes a high-gain observer design for a class of nonlinear systems with
multiple known time-varying delays intervening in the states and the inputs. In the free delay …

This paper deals with high-gain nonlinear observer design for a class of triangular systems
with delayed output measurements. Based on a recent high-gain like observer design …

A simple nonlinear observer with a dynamic gain is proposed for a class of bounded-state
nonlinear systems subject to state delay. By saturating the states of the observer …

In this paper, we propose a high-gain observer design for nonlinear systems with time-
varying delayed output measurements. Based on a recent high-gain like observer design …

The design of observers for nonlinear systems with unknown, time-varying, bounded delays,
on both state and input, still constitutes an open problem. In this technical note, we show …

A state observer is proposed for a class of uniformly observable systems involving bounded
disturbances. The system outputs are delayed with a known (time-varying) delay and their …

For the purpose to estimate the state of nonlinear continuous-time systems, we focus on the
increasing-gain observer regarded as generalization of the well-known high-gain observer …

A full-order state observer for a class of nonlinear continuous-time systems is presented as
generalization of the high-gain observer for having a time-varying gain that is let to be small …

This work presents a simple observer for triangular nonlinear systems with time varying
delayed output measurement. A sufficient condition ensuring the asymptotic convergence of …

In this contribution we propose a simple and useful approach to design observers for
discrete-time systems with delays in the state and output variables. The main feature is that …
