Abstract

Controlling complex nonlinear networks is largely an unsolved problem at the present. Existing works focused either on open-loop control strategies and their energy consumptions, or on closed-loop control schemes with an infinite-time duration. We articulate a finite-time, closed-loop controller with an eye toward the physical and mathematical underpinnings of the trade-off between control
time and energy as well as their dependence on the network parameters and structure. The closed-loop controller is tested on a large number of real systems including food webs, random ecosystems, and spiking neuronal networks. Our results represent a step forward in developing a rigorous and general framework to control nonlinear dynamical networks with a complex topology.
