Robustness of Synchronous Communication Protocols with Bounded Delay for Decentralized Discrete-Event Control

Recent work on modeling communication delay between communicating decentralized discrete-event controllers considers only the case when all observations are communicated. When this condition is relaxed, it may yet be possible to formulate communicating decentralized controllers that can solve the control problem. Instead of synthesizing reduced communication protocols under bounded delay, synchronous communication protocols (where not all observations are communicated) are examined for their robustness under conditions when only the upper bound for the delay is known.
