| 摘 要： | 借助于线性时变系统输入-输出有限时间稳定性的定义,对大型互联线性时变系统引入了输入-输出有限时间稳定性的概念。并对一类大型互联线性时变系统进行了分散状态反馈控制器设计,利用微分线性矩阵不等式（DLMI）的方法,提出一个充分条件,当反馈控制律作用于该系统时,闭环系统是输入-输出有限时间稳定的。并给出仿真算例说明该结论的可行性和有效性。

| Abstract: | The concept of input-output finite-time stability for large-scale interconnected linear time-varying systems is introduced by referring to the definition of input-output finite-time stability for linear time-varying systems.The design of decentralized state feedback controllers is given for a class of large-scale interconnected linear time-varying systems.A sufficient condition is provided by using differential linear matrix inequality(DLMI).When the feedback control laws are applied to the systems,the closed-loop systems are at the state of input-output finite-time stability.A simulation example illustrates the feasibility and effectiveness of the conclusion. |
