摘要
针对一类时滞Ikeda混沌系统,利用Lyapunov稳定和微分不等式,研究了其指数同步问题。基于线性矩阵不等式理论得到了指数同步的充分条件,给出了指数同步控制器的设计方法,利用混沌掩盖将该同步方法应用于保密通信。仿真表明,该方案具有同步速度快、鲁棒性良好等优良性能。
The exponential synchronization of Ikeda delayed chaotic systems is discussed. An exponential synchronization controller is designed based on Lyapunov stability theory and differential inequality. A sufficient condition of exponential synchronization is proposed by using the linear matrix inequality. The proposed method is applied to secure communications. Simulation shows that the proposed scheme has high speed and good robustness.
