Observer design of descriptor nonlinear system with nonlinear outputs by using W$^{1,2}$-optimality criterion
Résumé
This paper deals with nonlinear observer design for a class of nonlinear systems with nonlinear output measurements. The proposed methodology uses Linear Matrix Inequalities (LMIs) to handle the problem of W 1,2 -Convergence criterion. Some new assumptions and recent convenient Youngs formulation are used to get less conservative LMI conditions compared to the literature. Indeed, the obtained LMIs contain additional decision variables, which render the conditions more general. In addition, the class of systems studied in this paper is more general than those available in the literature in the same context.
