摘要:
根据基于第一原理的多故障诊断理论,针对具有固定测量点的连续物理系统,提出一种实用诊断算法. 算法分3步:①根据系统的结构和测量点分布等不变知识,离线识别最小冲突集候选; ②根据测量数据,在线确定最小冲突集合组; ③由系统的冲突集合组求出诊断集. 算法可大大节省时间资源,便于实时故障诊断.
Abstract:
Based on Reiter’s theory from first principles, a practical algorithm of multiple-fault diagnosis is proposed for the continuous physical system with the fixed measure points. The algorithm consists of three parts: Firstly, a collection of minimal conflict set candidates can be identified in off-line way only according to the system configuration and the sensor distribution; Secondly, the real-time observed data are used to confirm the minimal conflict sets from the conflict set candidates; Finally, the diagnosis set is identified based on the conflict sets. The proposed algorithm can be used effectively in the real-time diagnosis.
