摘要

本文介绍了一种故障检测与隔离算法及其在多传感器分散系统中的应用。我们认为分散式系统是一个本地处理器网络，其中通信仅在邻近节点之间执行。每个节点取局部观测值，利用卡尔曼滤波的信息形式计算局部信息贡献。然后进行沟通，并计算出一个全局估计。本文描述的故障和隔离技术是基于多个模型的使用，这些模型描述了故障产生时系统动力学的变化。

A failure detection and isolation algorithm for a decentralised multisensor system

This paper describes an algorithm for detecting and isolating failures and its application on a multisensor decentralized system. We consider decentralized systems as a network of local processors where communication is performed only between neighbouring nodes. Local observations are taken by each node, and using the information form of the Kalman filter, local information contributions are calculated. These are then communicated and a global estimate is computed. The failure and isolation technique described in this paper is based on the use of multiple models, which describe the changes on the system dynamics when a failure is produced.<>
