故障检测滤波器的同时故障分离

DETECTION OF SIMULTANEOUS FAULTS WITH FAILURE DETECTION FILERS

本文讨论利用故障检测滤波器对同时故障进行分离的问题。文中首先在系统所有事件矢量广义相互可检测条件下给出了同时故障可分离的充要条件及同时故障的分离算法,然后讨论了上述假设不满足情况下同时故障的分离问题。

This paper is concerned with the detection and isolation of simultaneous faults with failure detection filters. At first, the necessary and sufficient conditions for simultaneous faults being detectable and the isolation algorithm are given under the hypothesis that all the event vectors are generalized mutually detectable. The isolation of simultaneous faults in general situations is then discussed.
