摘　　要：针对状态可测的一类连续非线性时滞大系统的鲁棒分散控制问题,采用T-S模型对其进行建模。根据李雅普诺夫稳定性理论及大系统分散控制理论,基于线性矩阵不等式(LM I),利用分散化并行分布补偿(PDC)的方法设计控制器,给出了保证该非线性时滞大系统闭环渐近稳定的充分条件。The decentralized robust control problem was proposed for a class of continuous-time nonlinear large-scale systems with time-delay. The T-S fuzzy model was adopted for fuzzy modeling of the large-scale systems with time-delay. According to Lyapunov stability theory and decentralized control theory of large-scale systems, the scheme for designing decentralized fuzzy controller was made via LMI method and PDC. The sufficient condition that ensures the asymptotic stability of the whole fuzzy time-delay large-scale systems was proposed.
