Abstract:

This talk presents a framework for analysis and design of robust networked systems. The framework encompasses a broad class of dynamics, including first-order consensus dynamics, opinion dynamics with stubborn agents, leader-follower dynamics for formation control, and HVDC power networks with decentralized proportional control. I will first show how we can quantify performance for each of these dynamics in terms of resistance distances in a corresponding electrical network. I will then show how this resistance distance-based formulation can be used derive analytical solutions for many optimization and design problems over such networks. I will also draw connections between the resistance distance-based approach and classical network facility location problems; these connections allow facility location algorithms to be extended to dynamical systems. Finally, I will show that, in systems with second-order consensus dynamics, the biharmonic distance plays a similar role to that of resistance distance in first-order systems. Thus, by using biharmonic distance, our framework can be extended to the analysis of second-order systems.
