摘要
研究了一个新混沌系统的同步问题,基于李雅普诺夫稳定性理论,利用参数未知时自适应控制法以及激活控制法实现该系统的同步,并用归纳、推理以及仿真实验进一步证明了这些结论的正确性.最后,采用自适应混沌同步方法进行保密通信实验,实验结果表明,利用混沌掩盖可以有效地恢复出信息信号.
The synchrocontrol of a new chaotic system was studied. Based on Lyapunov stability theory, ada- pting control method and activated control method were used to realize the synchrocontrol when parameters were unknown. The smmm＇y, reasoning and simulation experiments further prove the correctness of this conclusion. Finally, adaptive methods of chaotic synchronization were used to experimentalize secret commu- nication. The findings show that using chaotic masking can effectively restore the information signal.
