摘要
提出了一种基于局部反馈校正的无重置联邦滤波器的设计方法,该联邦滤波器在保证组合导航系统的容错性能不变的同时可以提高系统的导航精度。该方法用于船用组合导航系统设计中,通过计算机仿真,并同Carlson提出的无重置联邦滤波器的仿真结果相比较,表明该方法精度高、容错性好,该方法现已成功应用于船用组合导航系统设计中。
A local feedback compensation FKF is presented in this paper. The fault-tolerant performance of local feedback compensation FKF is the same as no-reset FKF and its precision is better. The local feedback compensation FKF is applied in shipborne integrated navigation system. Compared with no-reset FKF presented by Carlson, the local feedback compensation FKF＇s merit is proved by computer simulation. The method mentioned in this paper has been successfully applied in a ship- borne integrated navigation systen~
