Multi-synchronization of chaos via linear output feedback strategy

摘要

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.
