多涡卷混沌振荡电路同步的实验研究

Experimental Studies on Synchronization for Muti-scroll Chaotic Circuits

以5涡卷混沌振荡器为例进行了单向、双向耦合同步实验研究,实验结果显示耦合同步法同步性能良好,具体表现为:实现简单方便,鲁棒性较好,且双向耦合比单向耦合同步性能更好。以5涡卷混沌振荡电路为例用脉冲同步法进行同步实验研究,结果表明:脉冲同步法在合理选择脉冲的频率(周期)、占空比及幅度参数的情况下,可使收、发端的混沌振荡电路保持同步,且抗干扰性能良好,RC乘积越小,同步性能越好,实验结果与仿真结果一致。

Experimental studies are conducted for five scroll chaotic oscillators in one-direction and two-direction coupling synchronization. The method is simple and robust in implementation, and the experimental results show that the performance of two-direction coupling system is better than that of one-direction coupling syste~ The experimental results of the five scroll chaotic oscillators with pulse synchronization indicate that the pulse synchronization method can be implemented well when the parameters of pulse are appropriately selected. The experimental results of the five scroll chaotic oscillators with bond-orbit synchronization indicate that the product of R and C is smaller, the performance of synchronization is better, the experimental result is consistent with simulation result.
