摘　　要：讨论了状态反馈控制器存在摄动的线性广义大系统的非脆弱分散控制问题,应用线性矩阵不等式(LMI)方法,针对控制器增益具有加法式摄动和乘法式摄动两种情形,分别给出了线性广义大系统非脆弱分散控制器存在的充分条件。该控制器是一组线性矩阵不等式(LMIs),利用该不等式的可行解设计了非脆弱分散状态反馈控制器,使得闭环系统成为正则、稳定且无脉冲模的系统。仿真实例的结果说明了该设计方法的可行性和有效性。The issue of non-fragile decentralized control is addressed under state feedback controller gain perturbation for singular large-scale systems. Sufficient conditions for the existence of the non-fragile decentralized controller are obtained under the two classes of gain perturbations, namely, additive and muhiplicative by linear matrix inequality （LMI） approach, respectively. They are a set of linear matrix inequalities （LMIs）. With the feasible answers of these inequalities, the non-fragile decentralized controller designs for singular large-scale system under the two classes of gain perturbations are given. The designed controllers are such that the closed-loop systems are regular, stable and impulse free. Finally, an illustrative example is given to show the feasibility and effectiveness of the design.
