Abstract

This brief investigates the hybrid observer design for a class of nonlinear switched systems in which the discrete part is governed by a Petri net. The proposed hybrid observer represents a combination of a continuous observer based on the second-order sliding mode approach and a discrete one based on an unknown input observer. An illustrative example ends this brief and shows the efficiency of the proposed approach.
