摘要
研究节点动态不同的两个复杂网络的外部同步问题。运用牵制控制方法,网络模型选取节点输出线性耦合模型,基于输出控制思想,设计结构简单的牵制控制器,对响应网络中的部分节点施加输出反馈控制,使得两个复杂动态网络达到外部同步,即实现响应网络与驱动网络的渐近同步。根据李雅普诺夫稳定性理论,推出相应的同步准则,得到控制器参数选择条件。仿真时,驱动网络和响应网络分别选取Lorenz系统和Lü系统,对全局耦合网络和最近邻耦合网络两个典型网络拓扑进行仿真,验证了所提方法的有效性。
Research the synchronization issue between two output-coupling chaotic complex networks with different node-dynamics. By using pinning control method, design output controUer with simple structure and apply output feedback control on part nodes of response network to get the outer synchronization between two coupled networks,that is,response network and driving network get asymptotic synchronization. The criteria for choosing control parameters are obtained based on Lyapunov stability. Taking the Lorenz＇ s system and Lu system as the nodes of driving network and response network respectively,numerical simulations arc given for two typical networks, global coupling network and the nearest neighbor coupling network. The results demonstrate the effectiveness of the proposed method.
