基于CEEMD-APSO-LSTM的步进电机故障诊断
Stepper Motor Fault Diagnosis Based on CEEMD-APSO-LSTM
摘要
Abstract
In view of the problem of reduced fault diagnosis accuracy caused by irrelevant data interference such as noise in the fault vibration signal of stepper motors,a fault diagnosis model for optimizing LSTM(Long Short-Term Memory Network)based on CEEMD(Complementary Ensemble Empirical Mode Decomposition)and APSO(Adaptive Particle Swarm Optimization)algorithm is proposed.To reduce the noise interference in one-di-mensional vibration data,the CEEMD(Complementary Ensemble Empirical Mode Decomposition)method is adopt-ed to decompose the data,and the most relevant fault features are extracted in combination with the Pearson correla-tion coefficient.Enhance the learning ability of the LSTM based on the attention mechanism,focus on key fault in-formation,and optimize the model parameters through the adaptive weight particle swarm optimization algorithm.The key fault components are input into the model,reconstructed and then output to achieve fault diagnosis.The ex-perimental results show that the accuracy rate of the CEEMD-APSO-LSTM fault diagnosis model is 99.6%,and the loss function value is 0.021 6.关键词
