Abstract:

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. [JP2]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.
