摘要
研究三个耦合时滞van del Pol振子的动力学性质。以时滞为参数,得到当时滞增加并穿越临界值时,系统的稳定性开关现象发生的区域。通过数值仿真,利用该前馈van del Pol振子实现微弱信号的振幅增强。
The dynamic properties of three feed-forward coupled van del Pol oscillators with delay are discussed. By taking the delay as a parameter,it is shown that as the time delay increases and crosses through the critical values,there exists the stability switches in the certain region. Furthermore,by numerical simulations,the results of the enhancement of the amplitude of the weak signal are presented by using this feed-forward coupled van del Pol oscillators.
