Online real-time health management for aerial fuel delivery system

  • 摘要: 针对机载燃油系统在线实时健康管理存在的观测信息不确定性、任务完成时限性的问题,研究了国内外最新健康管理算法,提出了机载燃油系统健康模型构建、在线实时推理的方法.该方法基于系统结构模型,采用面向对象方法构建BN(Bayesian Network)健康模型,并利用GVE(Global Variable Elimination)算法离线编译BN健康模型,构造AC(Arithmetic Circuit)健康模型.仿真结果表明:与BN健康模型相比,所设计的AC健康模型在观测信息存在不确定性的情况下,能够高精度在线诊断系统故障,也可以有效满足健康管理严格时限性要求.
