Abstract:

Existing computational methods for control and verification are applicable only to problems of modest size and do not scale to today’s network control systems. To overcome this limitation, in this talk we advocate: (1) deriving network level guarantees from the subsystems with a bottom-up compositional procedure, and (2) exploiting key structural network properties. We identify such properties in applications such as multi-agent robotic systems, vehicle traffic networks, and synthetic biology, and generalize them to broader classes of systems. In the first part of the talk we present a compositional methodology where we make use of input/output properties of the subsystems to derive network level stability, performance, and safety guarantees. In the second part we address more complex control specifications expressed in temporal logic and leverage formal methods for control synthesis. In particular we overcome obstacles to scalability in this procedure by exploiting monotone dynamics and demonstrate the results on vehicle traffic networks. In the third part we apply our compositional network analysis techniques to spatial pattern formation in biology, a phenomenon that is central to multicellular development where gene expression patterns enable distinct cell types to emerge.
