System Stability Aware Multicast Routing in Cyber Physical Systems

In this paper, multicast routing is studied for the networking of decentralized sensors and controllers in cyber physical systems. The challenge of system stability awareness is addressed by employing the theory of linear matrix inequalities, thus forming a novel framework for studying the communi- cation sub-system in cyber physical systems. Both cases of ignorable delay and non-negligible delay are discussed. The proposed framework is then applied in the context of voltage control in smart grid. Numerical simulations using a 4-bus smart grid model show that the proposed framework and algorithm can effectively stabilize cyber physical systems.
