摘　　要：本文讨论了几种典型时滞滤波器的频率不灵敏性和阻尼不灵敏性 ,并综合考虑频率和阻尼不确定性 ,提出了完全不灵敏性的概念 ,来全面评价时滞滤波器的鲁棒性 .对时滞滤波器的灵敏度等高线进行了分析 ,灵敏度等高线提供了一种快速有效的方法 ,来判断当系统存在不确定性时 。In the previous study of time delay filter insensitivity, most work has addressed only frequency modeling errors. In this paper, we consider modeling errors in damping as well and define a total insensitivity measure that incorporates both frequency and damping modeling errors. An analysis of several types of time delay filters show a different ordering in terms of their total insensitivity to frequency and damping modeling errors compared to previous studies. The acceptable vibration level sensitivity contours of various filters propose an effective and simple way to determine whether a rectangular uncertainty region is encompassed in the sensitivity contour.
