中文摘要

      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化问题。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，改进了Wu等人[3]的一些近期结果。

英文摘要

      This paper first gives a decentralized scheme for bounded input bounded output (BIBO) stabilization of a class of large-scale systems without perurbations 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 perurbations in the subsystem is considered and the bound of permissible perurbations 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.
