Modeling and Analysis of Networked Discrete Event Systems with Multiple Control Channels (2004.01876v1)

Abstract: In this paper, we propose a novel framework for modeling and analysis of networked discrete-event systems (DES). We assume that the plant is controlled by a feedback supervisor whose control decisions are subject to communication delays and losses. Furthermore, we consider a general setting where the supervisor sends control decisions to different actuators via different communication channels whose dynamics are independent. We provide a system theoretic approach by identifying the state-space of overall networked system and investigating the dynamic of the entire state-space. Our approach precisely specifies the roles of the supervisor, the communication channels and the actuators. Also, we compare the proposed networked DES model with the existing one and show that the proposed networked model captures physical situations of networked systems more precisely.
