针对参数不一致系统以及同步无法实现的系统,基于误差渐进稳定收敛到零的原理,提出参数自适应加反馈同步法.数值模拟表明,通过选择合适的反馈系数,能够成功地实现混沌同步,并进一步将结果推广到超混沌系统.

Synchronization chaos based on error toward zero asymptotically using parametric adaptive control plus variable feedback was proposed both for a class of systems with discrepant parameters and for the systems in which synchronization hasn't been obtained previously. The numerical simulation shows that chaotic systems can be synchronized successfully with the appropriable coefficients. Furthermore, the control law is extended to the hyperchaotic svstem.
