This article investigates functional interval observer based estimation methods for discrete-
time switched descriptor systems with disturbances. A functional observer is presented using …

Interval observers are constructed for discrete‐time systems. First, time‐invariant interval
observers are proposed for a family of nonlinear systems. Second, it is shown that, for any …

Interval observer design and related techniques have been researched and applied in many
engineering fields and continue to be an active research area in the estimation and control …

In this paper, the problem of design of interval observers for Linear Parameter-Varying (LPV)
systems, containing non-detectable or non-strongly-observable parts, is addressed. Firstly, a …

A Luenberger‐like functional interval observer for the linear systems with time‐varying
disturbances is developed in this study. First, as an extension of the definition of the general …

Interval state observers provide an estimate on the set of admissible values of the state
vector at each instant of time. Ideally, the size of the evaluated set is proportional to the …

In this article, the state estimation problem of a continuous-time linear time-invariant system
is investigated for the situation with unknown external disturbance and measurement noise …

Observer design for dynamical systems with both known and unknown time-varying
parameters is of significant interest in a number of real-world applications. This class of …

The main goal of this paper is to present a methodology to design interval observers for
discrete-time linear switched systems affected by bounded, but unknown disturbances. Two …

This paper deals with the design of interval observers for switched linear systems (SLS), a
class of hybrid systems. Under the assumption that the disturbances and the measurement …
