Abstract

Synchronization phenomena underlie stable operation of power grid, memory and cognition in the brain, and coordination of man-made networked systems. This chapter studies the problem of ensuring synchronization of phase oscillators by pinning a subset of catalyst nodes to a desired frequency and phase, with focus on the classical Kuramoto model of coupled oscillators. Threshold-based conditions for synchronization with external catalyst nodes are discussed, as well as efficient algorithms for verifying those conditions. A submodular optimization framework for selecting catalyst nodes to guarantee convergence to a stable synchronized state is introduced. A case study on synchronization of power grids is presented.
