基于PNN的飞机发动机故障诊断研究

Probabilistic Neural Network Based Aeroengine Fault Diagnosis

鉴于概率神经网络良好的分类性能,提出一种基于PNN的飞机发动机故障诊断方法,成功对三种典型飞机发动机转子故障做出了正确诊断。研究表明,PNN网络诊断准确,对测量噪声有良好的鲁棒性,具有较好的工程应用前景。

Probabilistic neural network is good at classifying, we proposed a new method for aeroengine fault diagnosis based on PNN, and it can diagnose three typical aeroengine rotor fault accurately. The study shows that PNN is robust for noise rejection and is able to meet the application requirements.
