研究了一类不确定分布时滞模糊系统的鲁棒H∞输出反馈控制问题。该系统由一个具有分布时滞和范数有界参数不确定性的状态空间Takagi-Sugeno模糊模型描述。目的是设计一个模糊动态输出反馈控制器，保证闭环系统的鲁棒渐近稳定性，并对所有容许的不确定性保证干扰衰减的H∞范数界约束。利用线性矩阵不等式，给出了该问题可解的一个充分条件。最后，仿真例子来说明所提出的设计方法的有效性。
This paper investigates the problem of robust H∞output feedback control for a class of uncertain fuzzy systems with distributed delays. The system is described by a state-space Takagi–Sugeno fuzzy model with distributed delays and norm-bounded parameter uncertainties. The aim is to design a fuzzy dynamic output feedback controller which ensures the robust asymptotic stability of the closed-loop system and guarantees an H∞norm bound constraint on disturbance attenuation for all admissible uncertainties. In terms of linear matrix inequalities, a sufficient condition for the solvability of this problem is presented. Finally, simulation examples are provided to illustrate the effectiveness of the proposed design approach.
