摘要
使用降阶方法,采用改进的广义投影同步把不同阶数混沌系统的同步转化为相同阶数混沌系统的同步.基于Lyapunov原理,给出了自适应控制器,进而实现了不同阶数混沌系统的广义投影同步.采用混沌遮掩的途径将同步的两个系统用于保密通信中.仿真结果表明,两个混沌系统无失真地恢复有用信号,可将其用在基于混沌同步的保密通信中.
Using subtract-order method and improved generalized projective synchronization,the problem of synchronization of different orders of chaotic systems is translated into the synchronization of systems of identical order. Based on Lyapunov stability theory, the research gives the expression of adaptive controller,achieves generalized projective synchronization of different order. Then this method is applied to secure communication through chaos masking, numerical simulations show that the information signal can be recovered undistorted when applying this method to secure communication.
