摘要
利用把线性时变系统作为分段定常系统来进行可观测性研究的方法,将初始对准的最优多位置法应用于光纤陀螺捷联系统,分析了多位置对准的可观测性,通过仿真说明将多位置法应用于光纤陀螺捷联系统是有效的。
This paper applies the observability analysis of a time-invariant system being replaced by piece-wise time-invariant system. Multiposition alignment of SINS (Strapdown Inertial Navigation System) is used in FOG SINS and the observability of multiposition alignment is analyzed. Finally, the simulation is made which shows that the proposed algorithm is effective.
