Abstract

Abstract: Electric rudder is one of the most essential equipment on an aircraft. The diagnosis of electric rudder faults is of great significance to the production of electric rudder. To this end, this paper proposes a fault diagnosis method based on back-Propagation neural network (BPNN), which optimizes the weights and biases of BPNN using the self-organizing differential hybrid biogeography-based optimization algorithm (SODEBBO), and completes the automatic classification of multiple faults in electric rudder testing. The self-organizing differential hybrid biogeography-based optimization algorithm optimized the BPNN (SODEBBO-BP) model is compared with other eight models, and the results show that the maximum accuracy of SODEBBO-BP algorithm is 0.9918, the precision is 0.9981, F1-Score is 0.9981, G-mean is 0.9853, and Kappa is 0.9643 compared with other eight models. The model proposed in this paper is validated by experimental study and can be applied to the production and maintenance of electric rudder in the future. Graphical Abstract: Unlabelled Image Highlights: Use neural networks to build classifiers for multi-classification detection of rudder faults. Propose a new electric rudder fault diagnosis model called SODEBBO-BP. Two operators and search strategy of BBO are innovatively improved. By comparing with several diagnostic models, it was demonstrated that SODEBBO-BP has high diagnostic accuracy, stability and efficiency.
