Special Issue Information

Dear Colleagues,

Elector-mechanical actuators (EMA) and sensors have been increasingly applied in aerospace due to their advantages of higher reliability, a lower weight and better maintainability. To guarantee the operational safety and reliability of EMAs and sensors, fault diagnosis and health management can be utilized to acquire reliable information on potential failures. Traditional machine learning (ML)-based fault diagnosis techniques are limited in their ability to process natural data in their raw form. In recent years, deep learning (DL) methods have been increasingly used in fault diagnosis and prediction. Deep learning is an algorithm based on data representation learning in machine learning. The most obvious difference between DL-based models and traditional DL-based models is that DL can learn the abstract representation features of the raw data automatically.

This Special Issue, “Fault Diagnosis and Prognosis for Electromechanical Actuators and Sensors”, seeks original research articles presenting novel approaches to DL-based fault diagnosis, DL-based fault prediction and health management using EMAs and sensors.

With the development of modern military technology, electrical drive technology has become a power source for modern artillery. In fault monitoring of a driving motor mounted on a piece of artillery, various sensors are susceptible to interference from the complex environment, both inside and outside the artillery itself. In this study, we creatively propose a fault diagnosis model based on an attention mechanism, the AdaBoost method and a wavelet noise reduction network to address the difficulty in obtaining high-quality motor signals in complex noisy interference environments. First, multiple fusion wavelet basis, soft thresholding, and index soft filter optimization were used to train multiple wavelet noise reduction networks that could recover sample signals under different noise conditions. Second, a convolutional neural network (CNN) classification module was added to construct end-to-end classification models that could correctly identify faults. The above basis classification models were then integrated into the AdaBoost method with an improved attention mechanism to develop a fault diagnosis model suitable for complex noisy environments. Finally, two experiments were conducted to validate the proposed method. Under motor signals with varying signal-to-noise ratios (SNRs) noises, the proposed method achieved an average accuracy of 92%, surpassing the conventional method by over 8.5%. Full article
