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,和Carlson提出的无重置联邦滤波器相比较,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。将提出的这一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,证明了该方法的优点。
This paper proposes a design method of local feedback compensation FKF. Comparing with no-reset FKF presented by Carlson, the fault-tolerance of the local feedback compensation FKF is the same as that of no-reset FKF and its precision is better. The local feedback compensation FKF is applied to the ship-borne integrated navigation system, through the computer simulation, comparing with the simulation result of the no-reset FKF presented by Carlson, the local feedback compensation FKF is better.
