摘要
首先分析陀螺故障模式和陀螺功能模块的连接关系,建立陀螺的多信号流图,根据多信号流图得到陀螺的关联矩阵,结合关联矩阵利用可检测和可分离的准则得到陀螺可诊断性分析的初步结果;对关联矩阵得到的故障模糊组,进一步采用改进的BHS-树进行分离,得到陀螺可诊断性的最终分析结果,并给出提高可诊断性的建议,以及给出用程序实现可诊断性分析与验证面临关键问题的处理方法.
The correlation matrix of gyros is built firstly based on analysis of gyro＇s fault model and the correlation between different gyro modules.Then a preliminary result of gyro model diagnosis is obtained using the detectability and separability theorems.Then the ambiguity group of correlation matrix is separated further via improved BHS-tree.Finally the diagnosability is evaluated by the proposed method.Some suggestions are presented to improve the diagnosability.Moreover,some approaches are given to resolve the key problems in programming for diagnosability analysis and validation.
