摘　　要：对一类不确定非线性互联系统,给出了一种模型参考跟踪分散模糊H∞控制方法.采用模糊不确定T-S模型对非线性不确定互联系统进行模糊建模,应用并行分布补偿算法(PDC)给出了模型参考跟踪分散模糊H∞控制的设计及算法.应用李亚普诺夫方法证明了模糊闭环分散系统的稳定性分析.仿真结果进一步验证了该方法的有效性.The decentralized fuzzy model reference tracking H∞ control for nonlinear interconnected systems is studied via fuzzy control method. An equivalent T-S fuzzy model which represents the nonlinear interconnected system is given. Then, a decentralized fuzzy model reference H∞ tracking controller design and algorithm are developed based on parallel distributed compensation. It is proved that the designed fuzzy control algorithm not only guarantees the stability of the nonlinear interconnected systems, but also achieves H∞ tracking control performance. A simulation example illustrates the effectiveness of the proposed method.
