摘　　要：研究了一类带有时滞的不确定离散时间模糊系统的鲁棒H∞滤波问题。模糊H∞滤波器的设计建立在T-S模糊模型上并能确保滤波误差系统的渐近稳定和给定的H∞性能指标。考虑了时滞的存在使得滤波器有更小的保守性,由线性矩阵不等式(LMI)给出滤波器存在的充分条件。最后,仿真算例验证了给出方法的有效性。The problem of robust H∞ filtering was investigated for a class of uncertain discrete-time fuzzy systems with time delays. The design of fuzzy H∞ filter is based on T-S fuzzy model, which assures asymptotic stability and prescribed H index for the error filtering system. The time delays are considered so that the filter has less conservatism, sufficient condition for the existence of filter is established in terms of linear matrix inequality. Finally, simulation example illustrates the effectiveness of proposed method.
