基于自适应多小波网络预测模型的飞控系统故障诊断仿真研究

Mechanic Fault Diagnosis Based on Adaptive Multi-wavelet Networks Prediction Model for Fighter

提出了一个基于自适应多小波网络预测模型的飞机机械故障诊断新方法,给出了自适应多小波网络的构造方法和训练算法。以某型飞机作动器为例的计算机仿真结果表明,该方法故障诊断的能力及实时性都得以提高。

It＇s very important to diagnose the mechanic faults of a fighter accurately in time. A novel diagnosis method based on adaptive multi-wavelet networks prediction model was proposed. The structure and training algorithm of this adaptive multi-wavelet networks were introduced. The simulation results of a type of fighter actuator show that the method is more efficient and exact in application to three kinds of common faults diagnosis of flight control system.
