摘要

The synchronization of chaotic nonlinear systems has attracted much attention in recent years. Practical applications are being realized in the area of secure communications. However, a few synchronization hyperchaos have been reported. We have extended the drive-response relationship scheme (DRRS) of chaotic synchronization proposed by Pecora and Carroll to hyperchaos in the complex Lorenz-Haken system. But sometimes the DRRS is impossible to realize in some practical systems. Because some kinds of nonlinear systems are difficult to be decomposed into stable and unstable parts inside the system due to physical/chemical and other essential processes such as laser field in the Lorenz system. There may be no relationship between drive and response in practical systems. To overcome the above difficulty, other kinds of hyperchaotic synchronization have to be considered.
