摘　　要：研究了9涡卷超混沌吸引子的同步问题.首先采用Lyapunov稳定性理论,证明了可以用3变量反馈实现两个9涡卷超混沌吸引子的同步,并进行了实验验证,然后用主动-被动法,相互耦合法及单变量反馈法实现了同步,最后,对这些同步方法做了比较.The synchronization of two 9-scroll hyperchaotic attractors is studied. First, the conclusion that the synchronization of two 9-scroll hyperchaotic attractors can be realized by using 3 variables＇ feedback is proved based on Lyapunov stability theory and verified using computer simulation, then, the active-passive, coupling and single variable＇s feedback methods are also used to realize the synchronization, the synchronization effects of these methods are compared.
