主子惯导舰上标定挠曲变形补偿方法综述

A Survey on Flexure Deformation Compensation Methods in Master/Slave INS Calibration

摘要:

挠曲变形是主/子惯导在线标定的一种重要误差源,对其补偿处理具有重要意义。首先,分析了挠曲变形的概念、特点及其对主/子惯导误差方程影响；其次,将现有补偿处理方法分为 3大类,分别为测量方法、机理建模方法和随机过程建模方法,并讨论了他们各自的优缺点；最后,探讨了挠曲变形补偿方法的发展方向。

Abstract:

Flexure deformation is an important error sources of master / slave INS online calibration. It is great significanceto compensation those errors. In the analysis of the flexure of the concept, characteristics and post-master INS equationsinfluence the process, the existing compensation processing methods were divided into three categories, namely, measure.ment method, mechanism modeling and stochastic processes modeling. Then the advantages and disadvantages were dis.cussed. Finally, the development direction of the flexure deformation compensation method was discussed.
