Synchronizing Hyperchaos by Variable Feedback Control

摘要

正 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 syn-chronization hyperchaos have been reported.We have extended the drive-response relationship scheme(DRRS)of chaotic synchronizationproposed by Pecora and Carroll to hyperchaos in the complex Lorenz-Haken system.But some-
