超混沌chen-lee系统引入一个非线性状态反馈控制，将混沌Chen-Lee系统构造成四维超混沌系统。将这个四维超混沌系统作为驱动系统。采用主动控制方法构造一个响应系统，进一步选择适当的控制器使驱动-响应系统达到有限时间同步。(Hyperchaotic chen-lee system into a nonlinear state feedback control, the chaos Chen-Lee system constructed four-dimensional hyperchaotic system. This four-dimensional hyperchaotic system as the drive system. Using active control methods to create a response system, to further select the appropriate controller to drive- response system to the finite time synchronization.)
