| 摘 要： | 通过对传统联邦滤波算法的研究,根据其存在的固有缺陷,提出了一种基于组合导航的快速联邦滤波算法.然后应用矩阵范数理论,推导出了令Neumann展开式收敛的强化条件,并且利用信息分配因子的选取加快了滤波的收敛速度.最后通过与传统联邦滤波算法的仿真对比,验证了本算法的鲁棒性和快速性.

| Abstract: | Focused on the natural defect of traditional federated filtering algorithm,a fast federated filtering(FFF) algorithm based on integrated navigation was proposed.Then a consolidated term which can make Neumann expansion convergent was deducted,and the filtering convergent velocity was aecelerated by selecting information distribution factor.Finally,by simulation comparision with the traditional federated algorithm(TFF),the robustness and rapidity of this algorithm were validated. |
