基于主动-被动同步方案,利用电路实验实现具有立方非线性项的离散超混沌系统在单相耦合条件下的多同步态.多同步态是指驱动系统和响应系统的各状态变量之间分别实现完全同步、反同步、广义同步等不同类型的同步态.从理论上确定驱动和响应系统实现多同步态的解析条件.设计并搭建离散超混沌系统电路,所得多同步态电路实验结果与理论分析及计算机数值模拟结果相符.
Experiments on synchronization of two hyperchaotic discrete circuit systems are presented. These two systems are uniaxially coupled with the active-passive synchronization scheme. The state variables of the coupled circuits can achieve different kinds of synchronizations, such as complete synchronization, generalized synchronization, complete anti-synchronization and generalized anti-synchronization. The analytical conditions for different synchronous states are obtained. The experimental results are consistent with the theoretical computation and numerical simulations.
