| 摘 要： | 设计了一种基于GPS辅助以DR和DM的组合导航定位的联邦滤波器,采用GPS、DR和DM组合导航定位的设计方案的基础上,提出一种先分散式再局部集中联邦滤波器并采用一种简化的自适应联邦滤波器算法对各定位数据进行融合优化,并进行了仿真.仿真结果表明本文设计的联邦卡尔曼滤波器自适应算法对多传感器系统进行数据处理,能够提供一种最佳估计途径,在容错、数据容量及降低系统费用等方面,都比集中卡尔曼滤波器更为优越,使误差进一步减小.该设计与一般的分散卡尔曼滤波器比较,在信息综合方面更加快捷.

| Abstract: | This paper designs a federal filter of navigation position system based on GPS with the assistant of DR/DM combination.On this basis,further introduces a new kind of federal filter with the constructer of dispersed but partially centralized,then blends and optimize those position data with an adaptive federal filter calculation,finally goes along the simulation.The simulation result indicated that this adaptive federal filter calculation designed processes the data of multisensor,can provide a good way of e... |
