| 摘 要： | 针对难以获得航天器控制系统的精确模型,采用基于知识的定性故障诊断方法也难以奏效的问题,采取定性/定量混合故障诊断的思路,将基于案例推理和等价空间故障诊断方法有机结合,建立定性/定量混合故障诊断模型,推出一种定性/定量混合故障诊断方法。以航天器姿态控制系统为对象进行故障诊断。验证结果表明,推出的定性/定量混合故障诊断方法能够发挥二者的优势,比任何单独一种方法的诊断效果都好。

| Abstract: | Because of the special characteristics of spacecraft attitude control system that its precision model is not available and the knowledge-based method is not effective for it,adopting qualitative/quantitative hybrid fault diagnosis and combining the case-based reasoning method with parity space,the qualitative/quantitative hybrid fault diagnosis method based on case-based reasoning and parity space is proposed in this paper.The method is based on building a qualitative/quantitative hybrid fault diagnosis mod... |
