摘要
针对运载火箭的惯性导航问题,以五冗余陀螺惯组为研究对象,讨论了捷联惯性测量组合冗余设计方案,以系统导航精度最优为性能指标,引入了三种性能指标函数,并分析了这三种性能指标函数在使用过程中的等价性,最后研究了三正交两斜置结构的五轴冗余惯组系统的最优配置方法,并在考虑到量测精度对配置影响的条件下,通过理论分析和计算得到了最优配置的安装角,具有较强的工程实用性。
Aimming at the navigation problem of launch vehicle,the paper discusses the redundant design scheme of the strapdown inertial measurement unit with pentad configuration gyrocomponents as the study object.Considering the navigation precision as the figure of merit,introduces three kinds of figure of merit for the performance,and analyzes the equivalence of them in the application,finally,studies the optimal configuration method of pentad redundant inertial system,which takes the form of three orthogonal axes and two skewed axes,then obtain the angle of the optimal configuration by theoretical analysis and calculation taking the influence of measure precision to the configuration into consideration.
