| 摘 要： | 根据Lyapunov稳定性理论结合线性矩阵不等式技巧，研究了一类时滞混沌神经网络的同步与反同步问题，设计了各自的状态反馈控制器，并从理论上实现了此类时滞混沌系统的同步与反同步。最后将此类混沌系统应用于保密通信，通过同步与反同步系统的切换，设计出具体的数字保密通信方案，数值仿真验证了该方法的有效性。

| Abstract: | Based on Lyapunov stability theory and linear matrix inequality technique, the synchronization and anti-synchronization problem for a class of chaotic neural networks with delay was discussed, their own state feedback controller were presented, also the synchronization and anti-synchronization of this class of time-delay chaotic systems were realized in theory. Finally, this class of chaotic system was applied to secure communication, by system switching between the synchronization and anti-synchronization, a specific digital secure communication scheme was designed. The numerical simulation results verify the effectiveness of the method. |
