本文提出了一种网络化线性系统分层分布式控制器的设计方法。分层分布式控制器的优点在于，闭环系统的L2性能随着单独稳定不相交子系统的局部控制器的性能的提高而提高。对于系统的设计，我们利用状态空间扩展，使我们能够处理与不相交的子系统和层次聚类子系统之间的干扰在一个易于处理的方式与状态变量。此外，通过集成具有良好的兼容性与结构化控制器的分层分布式观测器，我们建立了一个框架，以实现基于分布式观测器的分层分布式控制。所提出的控制系统的效率通过一个例子的电力网络。
In this paper, we propose a design method of hierarchical distributed controllers for networked linear systems. The hierarchical distributed controller has an advantage that an L2-performance of the closed-loop system improves as improving a performance of local controllers that stabilize disjoint subsystems individually. Towards systematic design, we utilize state-space expansion that enables us to deal with the state variables associated with disjoint subsystems and those associated with interference among hierarchically clustered subsystems in a tractable manner. Moreover, by the integration of a hierarchical distributed observer having good compatibility with the structured controller, we build a framework to implement an observer-based hierarchical distributed control. The efficiency of the proposed control system is shown through an example of power networks.
