Abstract

This paper deals with the problem of H∞ observer design for a class of descriptor nonlinear systems with nonlinear output measurements. The established result is broad and can be applied to many estimation problems in nonlinear systems, such as unknown input estimation, fault diagnosis and state estimation. Based on the introduction of new assumptions involving a rank condition that specifies a constraint between the numbers of allowed unknown inputs, nonlinear functions, states and the number of measurements, a new Linear Matrix Inequality condition (LMI) for observer design is proposed. The obtained LMI is more general and less conservative, from a feasibility point of view, than those existing in the literature.
