炮射导弹系统故障的模糊-免疫混合诊断策略

针对炮射导弹系统故障特点和故障诊断方法中存在的不足,提出基于模糊-免疫混合故障诊断方法。从理论上分析模糊-免疫诊断方法的可行性和创新性,给出故障诊断策略的总体方案,建立故障诊断的数学模型;以制导装置为例对故障产生的原因进行定量计算。诊断结果表明:该电路发生故障的主要原因是由保护电路引起;所提方法可解决在故障先验知识缺乏的情况下对炮射导弹系统故障的定量诊断。

Mixed Diagnosis Tactic on Fuzzy-Immunity of Gun-Launched Missile System

Aimed at the features of gun-launched missile system fault and scarcities of fault diagnosis methods, the fuzzy-immunity mixed fault diagnosis method is proposed. The feasibility and innovation is theoretically analyzed, the overall project of fuzzy-immunity fault diagnosis is given, the math model of fault diagnosis is established; Taking guidance device as an example, the fault reason is quantitatively calculated. The diagnosis result indicates that the main reason of this circuit fault is protecting circuit; this method can resolve quantitatively diagnosis for gun-launched missile fault in the lack of prior knowledge.
