| 摘 要： | 传统联邦卡尔曼滤波算法的高容错性是以牺牲精度为代价的,为此提出了改进的联邦滤波算法,采用分时融合反馈的联邦滤波信息分配方式,在提高系统容错性的同时兼顾导航精度和实时性,而且无融合反馈阶段延长了故障反应时间,提高了系统对渐变故障的检测能力,取得较为理想的结果.

| Abstract: | Aiming to solve the conflict between the tolerance and the accuracy,an improved federated filter is proposed and a time-sharing feedback federated filter is presented which is based on the information-sharing principle.The algorithm greatly improves the fault tolerance and keeps the accuracy and real-time as well.Thus,it is possible that the gradually changed fault can be accumulated big enough regarding the design of non-feedback phase.Moreover the capability of detecting soft-fault is improved,and the eff... |
