摘要
针对输出耦合复杂网络的同步控制,提出一种自适应牵制控制方法以实现复杂网络同步.不同于现有同步控制方法,该方法利用节点输出变量构造同步控制器,只需控制网络中的部分节点就可根据同步误差自适应地调节控制器增益.利用Lyapunov方法给出复杂网络同步准则.最后对小世界网络和无标度网络进行数值仿真,结果表明文中所设计的同步方法能有效实现复杂网络的同步.
An adaptive pinning control method is proposed for synchronization of a complex network coupled with output. Unlike existing synchrnization methods, output of a complex network is used to construct synchronization controllers, and the synchronization-controller gains are adapted according to synchronization errors, and only part of nodes need to be controlled in the complex network. Furthermore, synchronization criteria are achieved for a complex network on the basis of the Lyapunov stability theory. Numerical simulations are carried out for a small-world network and a scale-free network, the results showing effectiveness of the proposed scheme for synchronization of complex network.
