线性多级动态结构大系统的反馈镇定

本文研究一类由Ｎ个子系统组成的具有多级动态结构线性大系统的多级反馈镇定问题，这类系统的多级反馈可镇定性与相应地导出系统分散反馈可镇定性等价。利用这种等价性以及系统本身的结构特征，给出了这类大系统可多级反馈镇定的充分条件。对于给定系统，应用本文的结论判别其多级反馈可镇定性是比较容易的。

Stabilization of Linear Large Scale Systems with Multilevel Dynamic Structure

This paper considers stabilization problem of a class of linear large scale systems composed of Nsubsystems with multilevel dynamic structure. The stabilicability of this kind of systems using a multileveldynamic controller is equivalent to the decentralize stabilizability of a system induced from the oringnal system, according to the equivalence and the structural characterization of the system, sufficient conditions onthe stabilization of the class of the systems are established in the paper. Since the conditions only depends onthe subsystems and their interconnections, it is esay to examine the stabilizability for a given large scale system of the class by using the presented conditions.
