Abstract:

According to the theory of consistency fault diagnosis based on first theory, the max-normal diagnosis theory based on dimidiate- consistent test is proposed. It integrates the kernel theory of consistent fault diagnosis and abductive diagnosis, not only makes up the weakness to construct the conflict set in intelligent fault diagnosis based on model, but also decreases the number of the objects in the consistency test and shrinks the space of diagnosis. Diagnostic accuracy is so greatly improved, the theory has better application. Application example proves the efficiency of this theory.

Key words: fault diagnosis, abductive diagnosis, dimidiate-consistent test, max-normal diagnosis

摘要：

基于第一原理的一致性故障诊断原理，提出以二分相容检验为基础的最大正常故障诊断理论。该理论融合一致性故障诊断与溯因诊断的核心原理，弥补了基于模型的智能故障诊断理论中矛盾集构造研究的薄弱环节，减少相容性检验的对象，缩小诊断空间，提高诊断的准确性，具有较好应用性。应用实例验证了该理论的有效性。
