This paper deals with the problem of detecting the current configurations of hybrid mechatronic systems, where theevolution of the discrete part is governed by a Petri net. The considered class of systems may have several subsystems,with different dimensions, evolving at the same time. The current configurations are detected using an observerbased on the descriptor system theory. It is shown that the evolution of the discrete dynamics can be formulatedas a descriptor system. Necessary and sufficient conditions are derived in order to guarantee the uniqueness of thereconstruction of the discrete state of the system. The proposed observer is applied to a mechatronic system to showthe effectiveness of the proposed approach
