Abstract :
In this paper we develop and apply a robust interval observer to estimate the unknown variables of uncertain chaotic systems. Considering that bounds of the uncertainties are known, we propose an observer that computes guaranteed upper and lower bounds for the unknown variables. We show that practical estimation (observer based synchronization) is asymptotically reached with bounded interval estimates. The method is applied to the synchronization of Chua´s chaotic system
