The design of dynamic H∞ observer (DO) for non-linear Lipschitz systems with multiple time-
varying delays and disturbances is studied. Sufficient conditions for the existence of these …

This study explores the development of H∞ H _ ∞ dynamic observer (HDO) for discrete‐
time nonlinear systems (DTNLS) with time‐varying delay (TVD) and disturbances. The …

In this work, we have studied the problem of designing H∞ dynamic observers (HDO) for
discrete-time linear systems (DTLS) with time-varying delay (TVD) and disturbance. By …

Functional observers are the major alternative to many practical estimation problems where
full-order observers cannot be used. This paper introduces a generalized approach to …

We present a robust H∞ observer for a class of nonlinear discrete‐time systems. The class
under study includes an unknown time‐varying delay limited by upper and lower bounds, as …

This paper presents a new approach to design an H∞ dynamic observer (DO) for multi-
delayed linear systems subject to L 2-norm disturbances. This observer generalises the …

In this paper, we present a robust H∞ observer for a class of nonlinear and uncertain time-
delayed systems. To design the proposed observer, the time delay does not have to be …

In this paper, we address the problem of observer design for a class of Lipschitz nonlinear
discrete-time systems with time-delay. The main contribution lies in the use of a new …

Issues of observer design for a class of Lipschitz nonlinear discrete-time systems with time-
delay and disturbance input are addressed, where the Lipschitz condition is expressed in a …

This paper deals with the problem of H∞ observer design for a class of uncertain linear
systems with delayed state and parameter uncertainties. This problem aims at designing the …
