多分辨力传感器信息融合中的故障检测与恢复

Fault Detection and Recovery inMultiresolutional Sensor Data Fusion

首先建立了一个具有故障检测与隔离功能的分散式滤波器结构,讨论了传感器及局部滤波器的故障检测与隔离算法.然后研究了系统重构与故障恢复方法.在此基础上,通过引入小波变换提出了一种多分辨力传感器信息的动态融合方法.

This paper first gives the structure of decentralied filter which is of fault de-tection and isolation function, discusses FDl algorithm of sensors and local filters. Thenresearches the system reconstruction and fault recovery method. Lastly, a dynamic fu-sion method based on the wavelet transforms for multiresolutional sensor data is pre-sented.
