Abstract
This paper deals with the problem of state estimation for perturbed output nonlinear systems. A multiple models approach is used to describe such class of systems. Then a structure of Lyapunov based sliding mode multiple observer is presented. The stability proof of the observer is ensured by a suitable choice of estimation gains which are solutions of a set Linear Matrix Inequalities(LMI). The simulation results for the denitrification application demonstrate the effectiveness of the developed estimator scheme.
