摘要: 提出一种非线性延时反馈参数调制法来控制混沌/超混沌,给出了利用这种方法控制处于超混沌状态的双环掺铒光纤激光器的方案.数值模拟表明,只要延时时间和反馈强度合适就可以把双环掺铒光纤激光器从超混沌状态成功地控制到不同的周期状态.
Abstract: We present a method of nonlinear time-delay feedback modulating/parameter to control chaos/hyperchaos.A scheme of controlling the hyperchaotic dualring Er-doped fiber laser by using this method is proposed.Numerical simulation shows th at a hyperchaotic dual-ring Er-doped fiber laser can be successfully controlle d into different periodic states by this method only when the delay time and fee dback intensity are suitably matching.
