A predictive approach for networked control of discrete event systems
Shaolong Shu, Feng Lin · 2016
In this paper, we continue to investigate the networked control problem of discrete event systems. The problem is to find a networked supervisor so that the language generated by the supervised system is equal to a given specification language K, even when there are communication delays and losses in the observation channel and control channel between the plant and the supervisor. While the networked supervisor is not predictive, we propose a predictive networked supervisor in this paper, which predicts the impacts of communication delays and losses in control channel in determining control actions. We derive the existence condition for a predictive networked supervisor. We show that the predictive supervisor is better than the non-predictive supervisor and no other supervisors are better than the predictive supervisor.
