该滤波器的特点是考虑了系统参数的变化范围，系统残留振动的最大幅值在参数变化区间内相等，从而提高了时滞滤波器的鲁棒性，特别是当系统参数大范围变化时，时滞滤波器有更强的鲁棒性，能有效消除柔性系统的残留振动。

In real flight, multiple sensors of aircraft engine control system may fault at a time. In order to solve this problem, a revised multiple-failure-hypothesis based testing is investigated. This approach uses multiple Kalman filters, and each of Kalman filter is designed based on a specific hypothesis for detecting specific sensors fault, and then uses WSSR (Weighted Sum of Squared Residual) to deal with Kalman filter residuals, and residual signals are compared with threshold in order to make fault detection decisions. The simulation results show that the proposed method can be used to detect multiple sensors soft failures fast and accurately.
