Abstract:
The operation and management of complex engineering networks usually take a hierarchical structure: system-wide optimization that adapts to large but slow fluctuations, and distributed real-time control that reacts to fast but small fluctuations. We show that network dynamics with distributed control can usually be seen as optimization algorithm for solving a global optimization problem. This provides a new perspective to understanding collective behaviors arising from the interactions between local control and decision, and more importantly a way to engineer distributed control to achieve system-wide properties beyond stability. This tightly coupled design of system-wide optimization, distributed control, and network dynamics will be needed for complex engineering networks of the future that face relatively large but fast fluctuations. We will illustrate the idea and issues using examples from communication networks and power networks.
