Abstract

Robust coordination and organization in large ensembles of nonlinear oscillatory units play a vital role in a wide range of natural and engineered system. The control of self-organizing network-coupled systems has recently seen significant attention, but largely in the context of modifying or augmenting existing structures. This leaves a gap in our understanding of reactive control, where and how to design direct interventions, and what such control strategies may teach us about existing structures and dynamics. Here we study reactive control of coupled oscillator networks and demonstrate dual control strategies that may be implemented interchangeably to achieve synchronization. These differing strategies take advantage of different network properties, the first directly targeting oscillator that are difficult to entrain, and the second targeting oscillators with strong influence on others. Thus, in addition to enlarge strategies for network control, the different control sets shed light on the oscillators dynamical and structural roles within the system. We close with a demonstration of the applicability of dual control of a power grid dynamics.
