摘　　要：本文对一类不确定状态不可测非线性互联系统,给出了一种基于观测器的H∞模型参考跟踪分散输出反馈模糊控制方法.设计中,首先采用模糊不确定T-S模型对非线性互联系统进行模糊建模,在此基础上,给出模糊分散观测器的H∞设计和基于观测器的模型参考跟踪分散模糊控制的设计.应用李亚普诺夫和线性矩阵不等式方法给出了模糊分散系统稳定的充分条件.仿真结果进一步验证了所提出的模糊分散控制方法的有效性.A fuzzy decentralized model reference tracking H∞ output feedback control method for a class of nonlinear interconnected systems is studied based on state observer. First, an equivalent T-S fuzzy model represents the nonlinear interconnected system and fuzzy decentralized observer is designed. Then a decentralized fuzzy observer and model reference H∞ fuzzy controller based on the observer are developed. The sufficient conditions for the stability of the fuzzy decentralized system are proposed by using Lyapunov function combined with linear matrix inequality （LMI）. Finally, the simulation example is given to illustrate the effectiveness of the proposed methods.
