Synchronization constitutes one of the most fundamental collective dynamics across networked systems. Whether a system may synchronize depends on the internal unit dynamics as well as the topology and strength of their interactions. For chaotic units with certain interaction topologies synchronization might be impossible across all interaction strengths, meaning that these networks are non-synchronizable.
Here we propose the concept of interaction control, generalizing transient uncoupling, to induce desired collective dynamics in complex networks. Intriguingly, localizing interactions in phase space by a fixed control scheme enables stable synchronization across all connected networks regardless of topological constraints. Interaction control may thus ease the design of desired collective dynamics, even without knowledge of the networks exact interaction topology.
