摘要
介绍了多惯性仪表冗余惯性测量系统数据融合前的测量异常值去除、系统误差修正和一致性检验的基本方法。针对测量数据一致性检验,讨论了置信距离测度和信任度函数两种处理方法。仿真结果表明后者能更好地确定一致性的惯性仪表测量数据。
The basic methods for eliminating of abnormal value, system error amendment and consistency check using before data fusion of the redundant inertial measurement system of multi inertial instrument were introduced in this paper. The two methods of fiducial distance measure and confidence measure function for consistency check of the data measured were discussed. The simulation results showed that the consistency of the data for multi inertial instrument was much better determined using the latter one.
