基于无源化的细胞神经网络超混沌系统同步

根据细胞神经网络超混沌系统的特点，求得混沌驱动系统与响应系统之间的误差系统.基于该误差系统，提出了混沌系统的同步条件：使同步误差大范围渐近稳定，然后采用非线性系统的无源化方法设计了使误差系统大范围渐近稳定的反馈镇定器.四阶细胞神经网络超混沌系统的计算机仿真验证了该方法的有效性. 关键词： 混沌同步 误差系统 无源化 细胞神经网络超混沌系统     

Consensus protocol for multi-agent continuous systems

Based on the algebraic graph theory, the networked multi-agent continuous systems are investigated. Firstly, the digraph （directed graph） represents the topology of a networked system, and then a consensus convergence criterion of system is proposed. Secondly, the issue of stability of multi-agent systems and the consensus convergence problem of information states are all analysed. Furthermore, the consensus equilibrium point of system is proved to be global and asymptotically reach the convex combination of initial states. Finally, two examples are taken to show the effectiveness of the results obtained in this paper.
