摘　　要：基于稳定性理论设计了一种同步比例传输技术,用以实现具有时空混沌行为的激光网络对目标信号的同步比例传输.通过选择特定的Lyapunov函数,确定了网络节点控制输入的结构.同步过程中,目标信号允许在网络的任意一个节点输入.运用此项技术不但能够使激光网络按照比例传输因子的大小同步传输目标信号,而且网络的连接方式和节点数目不受任何条件的约束.仿真结果显示,网络的同步性能非常稳定.On the basis of stability theory, a synchronization proportion transmission technique is designed to realize the signal proportion transmission of a laser network with spatiotemporal chaotic behavior. Through selecting specific Lyapunov functions, the structure of network node control input is determined. In the synchronization process, the target signal can be input in any node of the network. Using this technology, not only can the laser network transfer synchronously the target signal according to the magnitude of the proportion factor, but also the connection of the network and the number of network nodes are not restricted by any conditions. The simulation results show that the synchronization performance of the network is very stable.
