摘要
应用线性控制系统的结构分解理论及奇异值分解法对惯导系统 (INS)初始对准过程中的可观测性进行了全面分析 ,深入研究和详细分析了各种状态组合对系统可观测性的影响 ,定量地得出了惯导系统最佳观测状态组合时的结构分解过程及最佳可观测的子系统 ,为进一步研究INS的快速精确对准方法奠定了理论基础。
For the first time, the observability of initial alignment of inertial navigation system (INS) is deeply studied and thoroughly analyzed by means of the decompose theory of the linear control system and the singular value decomposition method in this paper. All kinds of the possible state combination influencing the observability of the INS have been deeply studied and thoroughly analyzed. It has been received quantificationally that of the structural analysis process of the best state combination of the INS and the best observable son-space. This has established the academic base for further study on a fast and precise initial alignment method for the INS.
