Modern systems are dominantly characterized by interconnected network systems and integration of control, communications and computing. Communication systems introduce new types of uncertainties, especially network topology switching and random delays. In this presentation, we will first summarize Wiener’s work on cybernetics, followed by a highlight of digital communication schemes that lead to network structural switching and random delays. We will use highway autonomous vehicle examples of network systems to illustrate some recent advances, and highlight impact of communication-induced switching network topology and random delays on platoon performance and safety. Theoretical foundations for dealing with these issues are then summarized, including switching diffusion and functional Ito formula.
