CONSTRUCTIVE DESIGN OF UNKNOWN INPUT NONLINEAR OBSERVERS BY DISSIPATIVITY AND LMIS

Abstract The existence of Unknown Input Observers (UIO) for nonlinear systems has been characterized recently by the first authors of this note as an abstract incremental dissipativity property of the system. In this paper, it is shown that for a large class of systems this condition can be made computable by the use of LMI techniques, leading to a constructive design method of nonlinear UIOs.
