摘要
本文简述了高精度系统的可靠性(维持性能或性能退化)问题,并以应用了故障检测和冗余技术的惯导系统为例对其进行了论述。 在惯导系统中,通常用陀螺性能监控器来实现机内精度检测技术。当导航系统由多个等精度的惯导子系统构成时,利用这些子系统的可观测输出变量的表决监控可得到几种软件故障诊断技术。
This paper deals with the reliability of an inertial, navigation system,in which failure detection and redundancy management are applied.In an inertial navigation system, the bit technique is usually implemented by gyroscope performence monitoring. When navigation system consists of several inertial navigation subsystems with identical accuracy, the software failure detection techniques are developed by using voter monitoring for observable output variables of the subsystems.
