Abstract: The problem of the design of observers for a class of nonlinear Lipschitz descriptor systems with unknown inputs is considered. The objectives are twofolds. Firstly, the design of an unknown input observer for nonlinear descriptor systems is studied. Secondly, if the disturbance is not possible, robust observer for such systems is proposed. The existence conditions of these observers are given and proved. A detailed example is presented for the method.

Key words: unknown input observer , Lipschitz nonlinearity system, descriptor system
