陀螺仪冗余系统的方案配置及故障检测与识别

The Gyroscope Redundancy System Scheme with Fault Detection and Identification

讨论了四目二自由度陀螺仪捷联系统的余度最佳配置方案,提出了利用奇偶方程进行故障检测与识别的线性相关技术,得出了余度技术不仅能提高系统的可靠性,而且还能提供重复测量数据,并能利用最小二乘进行数据处理,求解角速率的最佳估值。

Discusses the redundant optimal scheme of four two-degree-freedom gyroscope strapdown system, and presents the linearity correlation technology that detects and identifies the fault making use of parity equation. Concludes that the redundant technology not only improving the system reliability but also providing repetitious data, by means of which gets the optimal angle velocity estimation value in virtue of least square method.
