Research on Wavelet Neural Network in Fault Diagnosis for Flight Control System

摘要：

A fault diagnosis method for flight control system (FCS) based on the wavelet neural network was given. The wavelet analysis was adopted to construct the wavelet neural network (WNN). The training algorithm of WNN was improved by adding adaptive learning rate and momentum factor. Simulation results about application of this network to sensor faults diagnosis for FCS were given. The results show that the diagnosis system built based on WNN has good convergence and robustness.
