摘　　要：针对一类状态和状态时滞具有不确定性的时滞系统,研究了该系统基于T-S模糊模型的鲁棒H_∞控制器的设计问题。采用线性矩阵不等式LMI的方法,设计一个包含状态变量导数的模糊控制器,得到了系统鲁棒镇定且满足H_∞性能指标的充分条件,此充分条件等价于一类线性矩阵不等式的可解性,通过仿真说明了控制器的有效性。The problem of robust H_∞ control is discussed for time-delay systems with parametric uncertainties.The fuzzy H_∞ controller depends not only on the state,but also on the derivative of state.The sufficient condition is given such that the system is asymptotically stable and the H$ performance is satisfied for fuzzy time-delay systems.This condition is equivalent to the solvability of a kind of linear matrix inequality.Simulation results show the effectiveness of the proposed method.
