摘　　要：研究关于具有离散和分布时滞的中立微分系统的时滞相关鲁棒H∞滤波问题。求得的滤波器是Luenberger观测器类型的,它能保证滤波系统的渐进稳定并能满足一个给定的H∞性能指标。用Lyapunov稳定性理论和广义模型转换来分析系统,欲使得该设计方法比已存在的设计方法有更小的保守性。给出的例子说明了此设计方法的有效性。This paper deals with the robust delay-dependent H∞ filtering problem for neutral differential systems with discrete and distributed delays. The resulting filter is of the Luenberger observer type, and it guarantees that the filtering system remains asymptotically stable and satisfies a prescribed H∞ performance level. The Lyapunov stability theory and the descriptor model transformation are used to analyse the system. The proposed design approach is expected to be less conservative as compared with existing design methods. Some examples are provided to demonstrate the validity of the proposed design approach.
