Fast Consensus Via Predictive Pinning Control
By incorporating some predictive mechanism into a few pinning nodes, we show that convergence procedure to con- sensus can be substantially accelerated in networks of intercon- nected dynamic agents while physically maintaining the network topology. Such an acceleration stems from the compression mech- anism of the eigenspectrum of the state matrix conferred by the predictive mechanism. This study provides a technical basis for the roles of some predictive mechanisms in widely-spread biolog- ical swarms,flocks,and consensus networks.From the engineering application point of view, inclusion of an efficient predictive mech- anism allows for a significant increase in the convergence speed to- wards consensus.
