Networked control of discrete event systems is investigated in our previous papers. In a networked control, the communication between the plant and supervisor is via shared communication networks, where communication delays and losses are unavoidable. Network observability is introduced to characterizes the condition under which observation delays and losses will have no adverse effect on networked...
Work on decentralized discrete-event control systems is extended to handle the case when, instead of always observing or never observing an event, a supervisor may observe only some occurrences of a particular event. Results include a necessary and sufficient condition for solving this version of the decentralized problem (which is analogous to the coobservability property used in the standard version...
