Traditional fault diagnosis methods mainly rely on a single sensor signal, such as vibration or generator current signals, thus it often leads to limited diagnosis accuracy, primarily when multiple faults exist at the same time. Considering the electromechanical coupling characteristics of the electromechanical drive system, different sensors usually contain correlated and complementary informatio...Show More
Current-based fault diagnosis has become a promising solution for electromechanical systems due to the low cost and easy access. However, most of the existing studies require additional signal processing or diagnostic expertise to preprocess the signals due to the effects of the fundamental component and electrical noise. It is challenging to extract effective fault-related features from the raw c...Show More
