摘要
针对航天飞行器姿控喷管故障的诊断问题,考虑姿控喷管开关组合与飞行器姿控力矩的关系,提出了姿控喷管故障诊断的查表法及其改进查表方法两种查表法诊断喷管故障,经仿真验证,所提方法能够快速诊断故障和确定故障位置及形式,且准确率高,并具有较好的工程应用价值。
Aiming at the fault diagnosis of attitude control nozzle of spacecraft,considering the relationship between the combination of attitude control nozzle switches and attitude control moment of spacecraft,two table look-up methods are proposed to diagnose the nozzle fault.The simulation results show that the proposed method has high accuracy and fast detection speed.
