摘要
多惯性仪表冗余惯性测量系统数据融合前需要进行一致性检验,为此首先介绍了Lou的多传感器一致性检验思路,研究了具有代表性的置信距离测度一致性检验方法,然后,针对其不足之处,提出了一种支持度函数一致性检验方法,详细讨论该方法的推导和使用。仿真结果表明该方法计算量小,能简便、快速地确定一致性的传感器数据。
Consistency check applied before data fusion of the redundant inertial measurement system with multiple inertial instruments is necessary, so Lou＇ s method about the check of multisensor consistency is introduced and a representative method of fiducial distance measure consistency check is studied. In view of the defects of Lou＇s method, a method for supporting measure function consistency check is proposed, and its derivation and operation are discussed detalledly. Simulation results show that few computations are needed by this method and consistency sensor data can be chosen conveniently and quickly.
