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 …

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 …

Motivated by constant parameter estimation in nonlinear models, as well as state
observation in dynamical systems, an adaptive observer is proposed for a class of nonlinear …

In this paper, a global finite-time observer is designed for a class of nonlinear systems with
non-Lipschitz conditions. Compared with the previous results, the observer designed in this …

This paper develops a new high-gain observer design method for nonlinear systems that
has a lower gain compared to the standard high-gain observer. This new observer, called …

We address the problem of state estimation for a class of nonlinear systems with
measurement noise in the context of feedback control. It is well-known that high-gain …

There exist semi-global and finite-time converging observers for nonlinear systems that are
uniformly observable and globally Lipschitzian. This was achieved with local finite-time …

A robust high-gain observer for state and unknown input estimations for a special class of
single-output nonlinear systems is developed in this article. Ensuring the observability of the …

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 …
