This brief investigates the hybrid observer design fora class of nonlinear switched systems in which the discrete part isgoverned by a Petri net. The proposed hybrid observer representsa combination of a continuous observer based on the second-ordersliding mode approach and a discrete one based on an unknowninput observer. An illustrative example ends this brief and showsthe efficiency of the proposed approach
