Experimental Evidence for Spatiotemporal Stability and Control of a One-Way Open CML

Abstract

We present an experimental evidence for spatiotemporal stability of a real one-way open coupled map lattice implemented by electronic circuits. Furthermore, it is shown that the decentralized delayed feedback control method can suppress the spatial instability and the spatiotemporal chaos in the coupled map lattice circuits.

An Experimental Suppression of Spatial Instability in One-Way Open Coupled Chua's Circuits

“…Konishi, Kokame and Hirata reported that the decentralized delayed feedback control (DDFC) method can stabilize chaotic behavior in a one-way open CML [Konishi et al, 1998[Konishi et al, , 2000a. Imai et al observed the instability in the electronic CML circuits, and demonstrated the suppression of the instability by the DDFC method [Imai et al, 2002]. Konishi et al [2000b] verified that the mechanism of the spatial instability in the CML can be extended to continuoustime systems.…”
