Abstract

This work presents new results of the investigations on the dynamics of double-layers (DLs) generated in a discharge-plasma system under external perturbations. In different ranges of the control parameter the dynamics of the DL structure can present different behaviors. The transition from a chaotic state to other one, due to a perturbation, can be controlled by the parameters of this perturbation. In certain conditions the DL-resulting state can be periodic or not. The experimental results are in agreement with the predictions of a model based on coupled Van der Pol oscillators..
