摘　　要：研究了一类带有时变时滞的双线性关联大系统的分散状态反馈控制问题。通过定义新型的Lyapunov函数,导出了闭环关联大系统时滞相关渐近稳定的充分条件。通过并行分布补偿算法(PDC)和求解线性矩阵不等式得到分散模糊控制器。理论证明和仿真例子都说明在所设计控制器的作用下,关联大系统是渐近稳定的。The decentralized state feedback control was studied for a kind of nonlinear interconnected systems with time-varying delay in both states and inputs.The delay-dependent stabilization sufficient conditions were derived for the whole close-loop fuzzy interconnected systems,by introducing a new Lyapunov functional.The corresponding decentralized fuzzy controller was gotten by using the parallel distribute compensation scheme and solving a set of linear matrix inequalities（LMIs）.Both the theory analysis and simulation example showed that the interconnected systems are getting stable under the action of the designed controller.
