Abstract

Multi-synchronization of chaotic systems based on the master-slave scheme as an extension of the dual synchronization problem is introduced. It is assumed that the only information available from the master systems is a linear combination of their state vectors. The design procedure for multi-synchronization through output feedback strategy is described and the sufficient condition is given. The performance of the proposed algorithm is numerically examined by applying it to the Chen-Lorenz-Rossler and the Duffing-Van der Pol chaotic systems. Simulation results show the effectiveness of the proposed scheme.
