SYNCHRONIZATION AND CONTROL OF SPATIALLY EXTENDED SYSTEMS USING SENSOR COUPLING

We investigate the problem of synchronizing and controlling spatially extended systems. For this purpose a coupling scheme is introduced, that allows to synchronize and control the dynamics with only a few driving signals which are spatial averages of local regions. We estimate the optimal arrangement of the coupling signals and compare them with their usual periodic arrangement. The application in controlling, e.g. suppression of chaos, is demonstrated.
