摘要
为保证组合导航系统能始终正常工作 ,故障的检测与隔离至关重要。研究表明 ,小波变换方法在检测系统硬故障方面具有很大优势。本文即以 INS/ GNSS组合导航系统为例对此进行了仿真研究 ,并提出了两种具体的检测方案。通过仿真和分析 。
To ensure that the integrated navigation system works normally,fault detection and isolation are very important.Researches show that wavelet transform method has great advantage on detecting system abrupt fault.The wavelet transform method for the abrupt fault detection of the INS/GNSS integrated navigation system was studied by simulation in this paper.Two specific detection plans were proposed and were compared by simulation and analysis.
