| 摘 要： | 对非线性光电延迟反馈系统的响应时间序列进行数值分析.模型反馈循环中加入带通滤波器，建立非线性光电延迟反馈系统的数学模型.用龙格-库塔数值分析方法，通过调节参数，发现两种产生混沌信号的路径.设置特定φ时，在低反馈增益情况下，系统输出快速方波信号或慢速周期震荡信号，随着反馈增益的增加，系统输出出现复杂周期信号或混沌breather现象；在高反馈增益时，系统输出从不同的动力特性变成混沌状态.

| Abstract: | Response time series of nonlinear optoelectronic delay feedback system is numerical analyzed. Broadband pass filter is inserted in feedback loop of model. Mathematical model of nonlinear optoelectronic delay feedback system is set up. Two routes to chaos are numerical analyzed by adjusting parameters of system. At specific φ, under condition of low feedback gain, fast square wave signal or slow cycle oscillation signal is observed. With increase of feedback gain, more complex periodic signal or chaos breather phenomenon is appeared. At higher feedback gain, output of system is from different dynamic regimes into chaos. |
