等离子体三波耦合系统的混沌控制

摘要

With the aid of the nonlinear characteristics of three-wave coupling in plasma,we analyzed the chaotic characteristics of three-wave coupling system in plasma and put forward the method of perturbation control.The perturbation method can control the coupling system to the different period through times cycle to the bifurcation.With the increase of perturbation amplitude,the system can be controlled to cycles 8,4,2 and 1.Then we realized chaotic control of three-wave coupling system in plasma.%针对等离子体三波耦合的非线性特性,分析等离子体三波耦合的混沌特性,提出一种微扰控制等离子体三波耦合系统混沌状态的方法。结果表明：用微扰法可将等离子体三波耦合系统由倍周期倒分岔控制到不同的周期态；随着微扰幅度的增加,可将系统控制到周期8、周期4、周期2进而达到稳定的周期1,从而实现对等离子体三波耦合系统的混沌控制。
