中文摘要：
研究了一类具有参数不确定性的关联模糊大系统的保性能控制问题，基于线性矩阵不等式（LMI）方法给出了该不确定性模糊大系统分散状态反馈保性能控制器的设计方案，所设计的分散状态反馈保性能控制器不但使得该不确定性模糊大系统闭环渐近稳定，而且使得其二次型性能指标的上界最小．最后通过一个数值例子说明了所提出方法的有效性．
英文摘要：
A practical system should possess stability and other performances. This paper describes the guaranteed cost control of interconnected fuzzy large-scale systems with parametric uncertainty and proposes a design scheme of the guaranteed-cost controller with decentralized state feedback via LMI （Linear Matrix Inequality） technology. The proposed controller not only ensures the asymptotic stability of the closed-loop uncertain fuzzy large-scale system but also minimizes the upper bound of the quadratic performance measure of the system. A numerical example is finally provided to reveal the validity of the proposed approach.
