摘　　要：讨论一类具有状态和输入时滞的不确定Takagi-Sugeno(T-S)模糊模型的H∞控制问题.采用并行分布补偿控制法(PDC),建立系统镇定的充分条件并给出了H∞鲁棒控制器的设计方法.该方法保证了模糊闭环系统内部渐近稳定并满足从干扰输入到控制输出的H∞范数界约束.仿真实例验证了该方法的有效性.The problem of the H∞ robust control of a class of uncertain Takagi-Sugeno （T-S） fuzzy model with state and input time delays was discussed. Several sufficient conditions for the stabilization in considered systems and the design procedures of H∞ controller were derived by using parallel distributed compensation （PDC）. The designed controller could make sure that the closed-loop system was asymptotically stable and the effect of the disturbance input on the controlled output was reduced to a prescribed H∞ norm level. Simulation results showed that the proposed method was effective.
