摘要
采用误差变量的线性组合对一类四维动态超混沌系统进行单向反馈控制,解析地证明了实现同步的可能性,从Lyapunov理论角度分析了对于四维动态系统采用单变量单向耦合的可行性,求出同步所需控制器要满足的条件。当驱动系统参数做周期变化时,用文中的控制器实现了两个超混沌系统很好同步。
A class of 4-dimension dynamic hyperchaotic systems can be synchronized under single directional feedback control of the linear combination of error variables. The possibility of system synchronization is proven by analytical deduction. Based on Lyapunov theory, the possibility of synchronization of 4D dynamic systems via single valuable uni-directional coupling is also analyzed as to obtain the necessary conditions that controller must be met for the synchronization of two hyperchaotic systems. It has been demonstrated that when the parameters of driving system vary periodically, two herperchaotic systems can be synchronized steadily by the proposed controller.
