Abstract

In this paper, we are studying the problem of global stabilization of a class of the Euler discretized nonlinear systems by means of an observer (Separation principle). More precisely, we are interested in a class of feedback linearizable and uniformly observable (observable for any input) systems. These systems satisfy a global condition of Lipschitz. Numeric simulations using a model of heat exchanger are given to highlight the performance of the proposed controller.
