网络系统的聚类控制:自由度概念
Control of Networked Systems by Clustering: The Degree of Freedom Concept
摘要:
我们解决网络系统中的局部通量重新分配问题。我们的目的是检测一个合适的集群,它是能够本地吸收的干扰,通过适当的重新分配其节点之间的控制负载,使没有外部节点受到影响。传统的聚类措施是不适合我们的目的,因为他们没有明确考虑到结构条件的干扰遏制。我们提出了一个新的措施的自由度的概念为集群的基础上,我们引入了一个启发式的程序来快速选择一组节点根据这一措施。最后,我们展示了该方法在直流微电网电压控制方面的应用。
英文摘要:
We address the problem of local flux redistribution in networked systems. The aim is to detect a suitable cluster which is able to locally adsorb a disturbance by means of an appropriate redistribution of control load among its nodes, such that no external node is affected. Traditional clustering measures are not suitable for our purpose, since they do not explicitly take into account the structural conditions for disturbance containment. We propose a new measure based on the concept of degree of freedom for a cluster, and we introduce a heuristic procedure to quickly select a set of nodes according to this measure. Finally, we show an application of the method in the context of DC microgrids voltage control.
