摘要
研究了具有不同时滞的两个不同结构的超混沌系统的广义函数投影滞后同步问题。基于Lyapunov稳定性定理和自适应控制方法,设计了非线性控制器,使得混沌驱动系统与响应系统按照期望的函数因子矩阵实现同步。将此方法用于基于混沌掩盖调制的保密通信中,数值仿真表明了该同步控制方法和保密通信方案的有效性。
Generalized function projective lag synchronization of different structure hyperchaotic systems with different time delays was studied. Based on Lyapunov stability theory and adaptive control method, the nonlinear controllers were designed, and the output of the drive system was proportionally lagging behind the output of the re- sponse system and ratio of the two systems was secure communication through chaotic synchronization method and the secure masking desired function scaling matrix. Then, this method was applied to modulation. Numerical simulations confirm that both the proposed communication scheme are effective
