摘要

在混沌通信系统工程化过程中, 要求实时信号接收处理, 实现收发两端系统的快速同步. 为解决该问题, 提出了以非线性控制器设计为基础的快速同步方案. 针对离散混沌系统, 采用Lyapunov函数同步法判定准则和反馈同步原理, 合理设计了响应系统中的非线性控制器. 仿真结果表明, 同步误差可快速地稳定于零点, 验证了该快速同步方法的正确性和有效性.%In chaotic communication engineering , signals are required to be received and processed in real-time, thus the need for fast synchronization .A fast synchronization scheme based on nonlinear controller design is put forward .The nonlinear controller in response system is designed for discrete chaotic systems by adopting the Lya -punov function method and feedback synchronization principle .The simulation results show that synchronization error can quickly stabilize to near zero , verifying the correctness and effectiveness of the fast synchronization method .
