摘　　要：在网络保密通信中,为了保证保密信息在网络中传输的安全性,提出一种新的有限时间同步控制策略,使得发送端网络与接收端网络能够在有限时间内实现广义输出同步,即发送端网络与接收端网络能在极短的时间内达到同步,并且双方网络满足一种非常复杂的函数关系,从而增加了第三方破解双方网络满足的关系,增强了信息传输的安全性和保密性。应用Lyapunov稳定性理论证明了发送端网络与接收端网络在设计的非线性控制器作用下是如何保证系统稳定性的。仿真实验采用Lorenz系统,结果表明,该网络结构满足无标度特性,在设计的非线性控制器下能够有效地实现有限时间广义输出同步。In the network secret communication,in order to guarantee the transmission security of secret information in network,a new finite-time synchronization control strategy is proposed to realize the generalized output synchronization from the sending-end network to receiving-end network in finite time,and ensure that the two networks can satisfy a complex function relationship in shortest time,so as to make the third party crack the relationship satisfying the two networks,and enhance the security and confidentiality of information transmission. According to the Lyapunov stability theory,how to guarantee the system stability of the sending-end network and receiving-end network by using the nonlinear controller was verified. The Lorenz system is used for simulation experiment. The simulation results show that the network structure satisfies the scale-free characteristic,and the nonlinear controller can realize the finite-time generalized output synchronization effectively.
