利用冗余测量值对船舶导航系统的故障检测与识别

FAULT DETECTION AND IDENTIFICATION OF MARINE NAVIGATION SYSTEM USING REDUNDANCY MEASURED VALUES

本文在论述了具有冗余测量值时检测量误差的逻辑比较法之后，讨论了具有对称配置的四个单自由度惯性敏感器（陀螺仪或加速度计）构成的冗金系统（简称4S系统）的最优配置和性能管理，利用动态解析余度法解决了4S系统的故障检测和识别，通过理论分析和计算机仿真证明是有效的。

After reviewing the logical comparison method of detection of measurement error when redundant measurement exists, this paper touches upon the optimal configuration and performance management of redundant balanced system (4S system) which is composed of four single freedom inertial sensors (gyro and accelerator), and then, the failure detection and identification of the 4S system are solved by using the dynamic analytic redundant method. The result of theoretical analysis and computer simulation shows that the methods are effective.
