Résumé:
In this paper an interval observer for Linear
Parameter-Varying (LPV) systems is proposed. The considered
systems are assumed to be subject to parameter uncertainties
and component faults whose effect can be approximated by
parameters deviations. Under some conditions, an interval
observer with discrete-time Luenberger structure is developed
to cope with uncertainties and faults ensuring guaranteed
bounds on the estimated states and their stability. The interval
observer design is based on assumption that the uncertainties
and the faults magnitudes are considered as unknown but
bounded. A numerical example shows the efficiency of the
proposed technique.
