A General Architecture for Decentralized Supervisory Control of Discrete-Event Systems

Abstract. We consider a generalized form of the conventional decentralized control architecture for discreteevent systems where the control actions of a set of supervisors can be ``fused'' using both union and intersection of enabled events. Namely, the supervisors agree a priori on choosing ``fusion by union'' for certain controllable events and ``fusion by intersection'' for certain other controllable events. We show that under this architecture, a larger class of languages can be achieved than before since a relaxed version of the notion of co-observability appears in the necessary and suf
