The goal of this technical note is to design interval observers for a class of nonlinear
continuous-time systems. The first part of this work shows that it is usually possible to design …

It is shown that, for any time-invariant exponentially stable linear system with additive
disturbances, time-varying exponentially stable interval observers can be constructed. The …

This paper investigates interval estimation methods for discrete-time linear time-invariant
systems. We propose a novel interval estimation method by integrating robust observer …

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 …

The problem of output stabilization of a class of nonlinear systems subject to parametric and
signal uncertainties is studied. First, an interval observer is designed estimating the set of …

This techical note deals with interval state observer design for time-varying discrete-time
systems. The problem of a similarity transformation computation which connects a (time …

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 …

This paper presents a distributed method for detecting and isolating the faults in multiagent
systems (MASs). First, for the output-feedback-based closed-loop MAS in normal case and …

A dynamic interval approach for the fast computation of robust adaptive thresholds for a
class of uncertain linear systems is the subject of this paper. An extension of recent results …

Interval observers are dynamic systems that provide upper and lower bounds of the true
state trajectories of systems. In this work we introduce a technique to design interval …
