The present paper shows that the amplitudes of oscillators in delay-coupled oscillator networks can be suppressed by switching the network topology at a rate much lower than the oscillator frequencies. The mechanism of suppression was clarified numerically, and a procedure for determining the connection parameters to induce suppression is presented. The analytical and numerical results were obtained with Stuart-Landau oscillators and were experimentally validated using double-scroll chaotic circuits.
本文表明，在延迟耦合振子网络中，通过以远低于振子频率的速率切换网络拓扑结构，可以抑制振子的振幅。从数值上阐明了抑制机制，并给出了确定用于产生抑制的连接参数的方法。解析和数值结果是通过斯图尔特-朗道振子获得的，并使用双涡卷混沌电路进行了实验验证。
