Study of BP-Adaboost Algorithm for Diagnosing Aircraft Cable Faults

In order to solve the problems of short circuit, open circuit, insulation and other faults in aviation cables, a fault diagnosis method based on the BP-Adaboost algorithm is proposed. The BP neural network is used as the weak classifier in the Adaboost algorithm, and many weak classifiers are composed a strong classifier with stronger classification performance to diagnose fault categories. The BP-Adaboost fault diagnosis model is established, and the BP-Adaboost algorithm is improved to adapt to the multi -classification of cables, so as to identify the short circuit, open circuit, and insulation faults in the aircraft cable as well as normal working conditions. The accuracy of classification is analyzed; the results of the algorithm are analyzed by MATLAB software, and the analysis results show that the improved BP-Adaboost 'algorithm has a relatively good classification performance for multi -class aviation cable fault diagnosis.
