Networked control has been used more and more widely in engineering systems. To study networked control for discrete event systems, network controllability and network observability are introduced in our previous work on networked supervisory control theory. In this paper, we investigate robust supervisory control for networked discrete event systems. We assume that the system to be controlled is...
An extended framework of discrete event systems with continuous-time variable is considered. The controllability and TLm(Gt)-closeness of timed languages, which are extended concepts of the conventional ones, are presented to show the necessary and sufficient conditions for the existences of nonblocking and robust nonblocking supervisors.
