Controlled Synchronizibility Analysis for Non-diffusively Coupled Complex Networks

摘要: 该文研究了非耗散耦合网络的受控同步能力问题。在分析非耗散耦合网络外耦合矩阵特征值分布规律的基础上,给出了非耗散耦合网络的同步控制律。发现外耦合矩阵最大最小特征值之差越小,网络受控同步能力越强,耦合强度越小,网络越有可能通过控制取得同步,但在某些情况下所需要的控制增益绝对值也越大。最后以Lorenz振子小世界网络在混沌轨道上的同步为例对相关结论的有效性进行了验证。Abstract: Controlled synchronizibility of non-diffusively coupled complex networks is studied. After the analysis of eigenvalues distribution of outer coupling matrix of non-diffusively coupled complex networks, control law for synchronize non-diffusively coupled complex networks is given. It is found that the smaller the distance between largest and smallest eigenvalues of outer coupling matrix, the stronger the controlled synchronizibility of non-diffusively coupled complex networks. It is also found that the smaller the coupling strength, the greater the possibility that the network can achieve controlled synchronization. However under certain condition a smaller coupling strength requires a larger control gain value. Finally a small-world network formed by coupled Lorenz oscillators which needs to be controlled to synchronize onto chaotic orbit is given as an example to illustrate the effectiveness of the results.
