A discrete interval observer for linear system: Application on a real process

Abstract

A discrete interval observers used for linear systems attacked by ignorant quantities that previously known only by its bounds, is the main goal for this paper. The most important condition that we are searching for always ensured is the cooperativity. To claim that, two methods are considered as a framework. The presented techniques values are illustrated in an example of simulation and by an application on a transesterification reactor. The obtained results show that it is feasible to have a cooperative dynamic for the observation errors either with a state transformation or by imposing a constraint.
