EPCN: Robust Control Architectures for Decentralized Uncertain Systems

2017 - presentpresent
This project develops mathematical theory and methodologies for the robust control of decentralized systems. Such systems include the power grid, traffic control, wireless networks, and many other application areas. Key features are that distributed information-gathering is taking place, but decision-making is often made locally using subsets of the available information. Optimal decentralized control is generally intractable, yet certain broad classes of problems can be efficiently solved. This project will leverage the solution structures of these tractable instances, and thereby elucidate universal architectures that allow for simple adaptations in the face of uncertainty in the subsystems or latency in their communication. To achieve this goal, the project will bring to bear tools and insights from the fields of optimal control, robust control, delayed systems, and decentralized control. The project is organized into three aims based on the nature of the uncertainty being considered: (I) delays within subsystems or inter-system latency, (II) structured uncertainties in the subsystems, and (III) adaptations to changing subsystems.
