用于GPS/SINS故障检测/隔离的ARTMAP模型

ARTMAP Model for Fault Detection/Isolation in the Integrated GPS/SINS Navigation System

故障检测／隔离对于保证组合导航系统的高可靠性是十分重要的。本文提出了一种用于ＧＰＳ／ＳＩＮＳ故障检测／隔离的神经元方法，根据状态、残差两种χ２检验法的实时结果检测故障，然后用一个ＡＲＴＭＡＰ模型确定故障所在位置，进行故障隔离。通过仿真，证明了这种方法的有效性。

Fault detection/isolation is very important in ensuring the high reliability of integrated navigation systems.This paper presents a neuron approach to detect/isolate the faults in the integrated GPS/SINS navigation system.The system detects the faults according to the online results of the state chisquare test and the residual chisquare test,then an ARTMAP neural network model identifies the location of the fault and isolates it.Simulation results prove that this method is available.
