大系统的BIBO稳定性

BIBO Stabilization of Large-Scale Systems

本文首先给出了一类大系统有界输入有界输出（ＢＩＢＯ）稳定化的一种分散控制方案．其可稳定化的条件仅仅是其子系统一致完全可控．然后考虑了每个子系统含有非线性摄动的大系统鲁棒稳定比问题．其摄动的允许界通过局部状态反馈获得．最后应用获得的结果到线性单系统。

This paper first gives a decentralized scheme for bounded input bounded output(BIBO)stabilization of a class of large-scale systems without perturbations in each subsystem,the only stabilizability condition is the uniform complete controllability of the subsystems. Then the problem of robust BIBO stabilization of the large-scale systems with nonlinearly perturbations in the subsystems is considered and the bound of permissible perturbations is obtained by using a stabilizing local state feedback. Finally,we apply the obtained results to the single linear system and improve a previous result.
