Synchronization of unidirectional coupled chaotic systems via partial stability

Abstract

Chaos synchronization can be achieved by several methods but there is no easy unified criterion in general. In this paper, a general scheme is proposed to achieve chaos synchronization via stability with respect to partial variables. Three theorems for synchronization of unidirectional coupled non-autonomous (also autonomous) systems by linear feedback are developed for systems with and without system structure perturbations. The system, fly-ball governor, is demonstrated as an example. (C) 2003 Elsevier Ltd. All rights reserved.
