研究了导航系统的故障检测问题。在数学上，这个问题被表述为对随机过程中突变的最快检测。为了解决这一问题，提出了改进的累积和算法（CUSUM）。实验证明了该算法对软（漂移型）故障的检测能力及其在惯性导航系统和惯性/无线电导航系统监测中的应用。本文报道了CUSUM算法在某新型飞机试飞实验数据中的应用结果。
The fault detection problem for a navigation system is investigated. Mathematically this problem is formulated as that of the quickest detection of abrupt changes in a stochastic process. For solving this problem the modified cumulative sum algorithm (CUSUM) is proposed. The ability of the proposed algorithm to detect soft (drifting-type) faults and its application for the monitoring of the inertial and the inertial/radio navigation systems are demonstrated. Test results describing the application of CUSUM algorithms to experimental data from test flights of a new airplane are reported.
