This paper deals with the problem of the estimation of non-uniformly nonlinear systems with time-varying delays in the state and input. In addition, the problem of the sampled output measurement is also been addressed. Thus, an observer design for a

This paper provides a redesigned version of the Standard High Gain Observer (SHGO) to cope with the peaking phenomenon occurring during the transient periods as well as the sensitivity to high frequency measurement noise. The observer design is perfo

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 measurements are continuously available over some time horizons and sa

This paper deals with the design of a Filtered High Gain Observer (FHGO) for a class of uniformly observable systems involving uncertainties. The structure of the proposed observer is very simple as it consists in two cascaded sub-systems of the same

In this paper, a state observer is proposed for a class of nonlinear systems in the presence of uncertainties in the state equations and an arbitrarily long delay in the output. The proposed predictor has a cascade structure in such a way that the fi

This paper is concerned with the design of an observer for a large class of non-uniformly observable MIMO systems, whose structure is not the classical triangular one. The main features allowing the construction of the observer are the introduction o
