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 …

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 …

An interval observer for Linear Time-Varying (LTV) systems is proposed in this paper.
Usually, the design of such observers is based on monotone systems theory. Monotone …

For a family of nonlinear discrete-time systems with input, output and uncertain terms, a new
interval observer is designed. Its main feature is that it is composed of two copies of classical …

We consider continuous-time systems with input, output and additive disturbances in the
particular case where the measurements are only available at discrete instants and have …

Some applications in control require the state vector of a system to be expressed in the
appropriate coordinates so as to satisfy to some mathematical properties which constrain the …

For a family of continuous-time nonlinear systems with input, output and uncertain terms, a
new interval observer design is proposed. The main feature of the constructed interval …

This technical note deals with the design of stable interval observers and estimators for
continuous-time linear dynamic systems under uncertain initial states and uncertain inputs …

This paper deals with the design of an interval state estimator for linear time-varying (LTV)
discrete-time systems subject to component faults and uncertainties. These component …

A family of continuous-time observable nonlinear systems with input and output is
considered. A new technique of estimation of the state variables is proposed. It relies on the …
