| 摘 要： | 对于一个新的四维超混沌系统，通过相平面分析和Lyapunov计算对其进行了简单的分析。基于Lyapunov稳定性理论和Babalat引理，设计出适当的控制器和相应的参数自适应律，最终实现了两个同样的参数完全未知的该超混沌系统的全局同步。数值模拟结果证明了该控制器设计的有效性。

| Abstract: | For a novel four-dimensional hyperchaos,we analyzed its complex properties by phase portrait and computing Lyapunov exponent.Based on Lyapunov stability theorem and Babalat's lemma the appropriate controller and parameter adaptive law were designed so as to synchronize the two identical hyperchaotic systems with unknown parameters.Simulation results were proposed to demonstrate the effectiveness of the controller. |
