单变量反馈实现3涡卷超混沌吸引子的同步

文献1]在四阶MCK电路的基础上提出了产生N(N=3，4，5，…)涡卷超混沌吸引子的方法，采用4变量反馈实现了两个N-涡卷超混沌吸引子的同步。为了减少同步所需驱动信号的个数，采用Lyapunov稳定性理论证明了反馈变量可以减少为3个，以3涡卷超混沌吸引子为例验证了这一结论，并进一步通过数值仿真用单变量反馈的方法实现了3涡卷超混沌吸引子的同步，节约了信道资源，为实际应用提供了方便。

Synchronization of 3-scroll Hyperchaotic Attractors Using Single Variable's Feedback

In previous works, a method of generating N-scroll hyperchaotic attractors based on the MCK circuit is presented, the synchronization of two N-scroll hyperchaotic attractors is studied using 4 variables' feedback. In order to decrease the number of driving variables,the conclusion that the synchronization can be realized by using 3 variables' feedback is proved based on Lyapunov stability theory and verified using 3-scroll hyperchaotic attractors. Furthermore, computer simulation also indicates that the synchronization of two 3-scroll hyperchaotic attractors can be realized by using single variable's feedback, the channel resource is saved,thus facilitate practical application.
