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