基于案例的推理技术在故障诊断中的应用

Application of the Case-Based Reasoning for Fault Diagnosis

将航天器故障诊断系统中的预案设计与基于案例推理的故障诊断技术相结合,提出了基于预案设计的故障诊断思想,给出了预案的规范化定义,并以某卫星能源系统故障模拟试验台为对象,对诊断模型进行了验证,为解决航天器故障诊断系统知识不足的问题作了新的尝试.

In this paper, the idea of fault diagnosis based on pre-case design is put forward through combining the pre-case technology with case-based reasoning. A standard definition about pre-case is built. The diagnosis model is verified in the test-bed of a satellite power system. This is a new test for spacecraft′s fault diagnosis.
