摘　　要：研究了基于动态输出反馈的不确定关联时滞系统的分散保成本控制问题 ,其不确定性是范数有界的 .给定积分二次型成本函数 ,采用 Lyapunov稳定性理论导出了输出反馈分散保成本控制律存在的充分条件 ,该控制律的设计问题最终转化为一组线性矩阵不等式 (LMI)的可行解问题 .This paper is concerned with the problem of decentralized guaranteed cost control for a class of norm-bounded uncertain interconnected systems with time-delay based on output feedback. Given a quadratic cost performance, a sufficient condition for the existence of decentralized guaranteed cost output feedback controller is derived by Lyapunov stability theory. The design of this controller is transformed into a problem of finding a feasible solution for a set of LMI.
