摘要

本文提出了一种2/sup和1 / order滤波器故障建模的功能方法，并提出了暂态分析方法在故障检测中的新应用。该方法将滤波器视为一个2/sup和/阶动态系统，并使用峰值时间和系统超调作为观察参数。输入刺激是由阶跃、斜坡或抛物线组成的紧凑测试向量。结果表明，该方法可检测出100%的软故障。

Fault detection methodology for second order filters using compact test vectors transient analysis

This work proposes a functional approach for fault modeling in 2/sup nd/ order filters and presents a new use for the transient analysis method for fault detection. The approach considers the filter as a 2/sup nd/ order dynamic system and the use of the peak time and the system overshoot as observed parameters. The input stimuli are compact test vectors which consist of a step, ramp or parabola. The obtained results show that 100% of soft faults can be detected.
