航空发动机故障诊断算法测试平台

在MATLAB/Simulink环境下搭建航空发动机故障诊断算法测试平台。利用已有的民用大涵道比涡扇发动机非线性模型进行仿真得到航空发动机故障数据,数据既可以用于故障诊断算法的开发,也可以用于故障诊断算法的验证。对用户提供的故障诊断算法按照统一的评价标准进行分析,得出诊断算法优良性的量化值,使得不同结构、不同平台的诊断算法能直接作出比较。通过故障诊断算法的诊断结果进行分析,得到的评价结果可全面反映故障诊断算法的性能。

A Evaluation Platform Based on Aeroengine Fault Diagnostic Algorithm

This paper described a platform that can evaluate aeroengine fault diagnostic algorithm,which is established in MATLAB/Simulink environment.A high bypass ratio turbofan nonlinear engine model was used to simulate engine fault data,which can be used for fault diagnosing and algorithms identifying.A quantized performance value of fault diagnostic algorithm could be obtained according a unification standard,which enables different fault diagnostic algorithms can be compared directly.By evaluating a fault algorithm′s diagnostic assessment,the evaluation can reflect the fault algorithm′s performance.
