Exact controllability of complex networks [PDF]

open access: yesNature Communications, 2013
Controlling complex networks is of paramount importance in science and engineering. Despite the recent development of structural-controllability theory, we continue to lack a framework to control undirected complex networks, especially given link weights.

Exact controllability of multiplex networks

open access: yesNew Journal of Physics, 2014
We develop a general framework to analyze the controllability of multiplex networks using multiple-relation networks and multiple-layer networks with interlayer couplings as two classes of prototypical systems.

Shape, Velocity, and Exact Controllability for the Wave Equation

open access: yesJournal of Optimization, Differential Equations and Their Applications, 2022
A new method to prove exact controllability for the wave equation is demonstrated and discussed on several examples. The method of proof first uses a dynamical argument to prove shape controllability and velocity controllability, thereby solving their ...
