Résumé

This paper deals with the problem of the state estimation of discrete time nonlinear systems described by Takagi-Sugeno structure with unmeasurable premise variables. The proposed observer design method is based on the use of the second method of Lyapunov and a quadratic function. Based on this procedure two methods are proposed. The convergence conditions of the observer are expressed in terms of Linear Matrix Inequalities (LMI). Finally, these two methods are compared with regard to their domains of validity.
