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 …

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 …

This paper presents a state observer for drift observable nonlinear systems when output
measurements are affected by a known and bounded time varying delay. The structure of …

We design observers for nonlinear systems with sampled and delayed output
measurements. The observers are of continuous and hybrid in nature. Based on an auxiliary …

The article presents a new approach for the construction of a state observer for nonlinear
systems when the output measurements are available for computations after a nonnegligible …

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 …

This paper considers the state observer problem for a class of nonlinear systems, which
present multiple noncommensurate time delays as well as distributed delay terms. The …

This paper proposes a state observer with a cascade structure for a class of nonlinear
systems in the presence of uncertainties in the state equations and an arbitrarily long delay …
