采用共轭变量耦合方式构造了以Sprott—J模型为子系统的耦合系统,讨论等同和参数失配条件下耦合系统的振荡消失问题,给出理论解析判据,用数值计算方法验证其正确性.设计出该耦合系统的电路,通过Pspice仿真平台实现了实验系统的振荡消失.
The amplitude death phenomena in both identical and mismatched coupled Sprott-J systems are investi- gated. The conditions for amplitude death are analytically determined and are numerically confirmed. We construct the circuit of coupled Sprott-J systems and find the same phenomena of amplitude death through PSpice software simulations.
