| Abstract: | Fault tolerance and diagnosis technology is an effective method to improve the accuracy of the navigation system and the reliability of control system, the fault diagnosis technology in strapdown navigation system has been widely used in the control system of launch vehicle(LV). In this paper, a fault diagnosis and decision method is proposed for the 10-meter-configuration of LV, and on this basis, the scheme of information reconstruction and the threshold of fault diagnosis are designed. The results of mathematical simulation show that the faults of meters can be rapidly diagnosed through this method. It also can output the right information reconstruction of meters in the event of a fault to provide the mission and is worthy for practical engineering applications. |
