电罗经故障诊断技术研究

简要介绍了模糊集理论,并针对某型电罗经故障发生概率具有模糊性和不确定性的特点,将模糊集理论引入故障树分析,对电罗经各个环节发生故障时所遇到的各种模糊信息进行了科学、定量的处理.试验证明,该方法能够解决传统故障树分析不能处理同时存在随机不确定性和模糊不确定性的故障事件的问题.

Research on the Fault Diagnosis of Gyro Compass

In this paper, the fuzzy-set theory is introduced briefly, and aiming at the feature that the occurrence probability of fault event in certain type gyro compass usually shows fuzzy and random, the fuzzy-set theory is inducted into the fault tree analysis. The fuzzy information collected from the faults occurred in various part is scientifically and quantitatively processed. It could be concluded that this is an efficient fault analysis approach over the conventional one for handling random and fuzzy problems.
