DECENTRALIZED DELAYED FEEDBACK CONTROL OF COUPLED MAP LATTICES ON IRREGULAR NETWORK TOPOLOGIES

This paper proposes decentralized delayed feedback control for coupled map lattices on irregular network topologies. Linear stability analysis provides a systematic procedure for designing controllers that does not depend on the number of sites or network topology. To reduce the long waiting time for stabilization, we demonstrate two techniques by numerical simulations: delayed feedback destabilization and time-varying coupling-strength. Furthermore, the robustness of the controlled state against external disturbances is investigated.
