Abstract: The control of large-scale networks is a pressing problem of relevance to numerous natural and engineered systems. Despite recent advances in network and control science, there has been a lack of fundamental understanding of the network properties that can enable efficient and effective control of such systems. In this presentation, I will introduce a notion of network locality and demonstrate that the property of being localized is common across numerous network systems. I will then show that this property can be exploited to dramatically improve our ability to control large-scale networks, including networks with nonlinear dynamics. Illustrative examples will include synchronization dynamics in the Eastern US power grid, epidemic spreading mediated by the global air-transportation network, and Alzheimer’s disease dynamics in a human brain network. Our results establish that large networks can be controlled with computation and communication costs comparable to those of small networks.
