摘要 针对Lorenz混沌系统,采用变量z单向耦合的方法,构建了驱动响应系统,对系统的同步现象进行了仿真研究.设计了脉冲控制器,实现了正反相同步间的动态切换.通过分别计算正相同步与反相同步的最大横向李雅普诺夫指数来判断其切换前后同步平面的稳定性,并找出了稳定同步平面的耦合强度临界值.计算机仿真结果表明:在一定的参数范围内,驱动系统和响应系统能够达到正相同步或反相同步.系统能否达到这两种同步状态取决于系统初值和耦合强度.数值仿真结果进一步验证了该方案的有效性,并且可以根据实际需要实现正反相同步切换. Coupled by variable z, the drive-response system of Lorenz is realized. Some chaotic synchronization states are also investigated. The impulsive controller is designed to switch the in-phase synchronization state and the anti-phase synchronization state. Stability of in-phase synchronization and anti-phase synchronization manifolds before and after dynamic switching is analyzed by calculating the maximum transversal Lyapunov exponent (MTLE), The critical value of coupled strength for stable synchronization manifold is derived. The computer numerical simulation shows that in-phase synchronization state or anti-phase synchronization state has been in drive -response system with parameters in some regions. The stability of in-phase synchronization or anti-phase synchronization state is determined by the initials and the coupled strength. Numerical simulation results have shown that the scheme is effective, and the in-phase synchronization state and the anti-phase synchronization state can be switched by the system according to the actual demand.
