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。 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.
