受控Gibbs激光系统动力学行为的仿真研究

摘要

研究了受控Gibbs激光系统的动力学行为。首先介绍了Gibbs激光系统模型，给出了Gibbs激光系统的Lyapunov指数随参数的演化图像以及与之对应的系统状态变量与参数的关系曲线。进一步仿真模拟了反馈信号强度对系统动力学行为的影响。结果显示，通过调节反馈信号强度，系统存在倍周期分岔、周期并合以及混沌等多种非线性效应。%The dynamical behavior of controlled Gibbs laser system is researched. Gibbs laser system model is introduced at first. The images from Lyapunov exponent of Gibbs laser system changing with incident light intensity parameters and the relationship curve of the relative system state variable and incident light intensity parameters are given. The influence on system dynamical behavior from feedback signal intensity is simulated further. The re⁃sults show that nonlinear effects such as double periodic bifurcation, periodic combination and chaos through regu⁃lating feedback signal strength exist in the system.
