Remaining useful life (RUL) prediction of rolling bearings is great importance in improving the reliability and durability rotating machinery. This paper proposes a dual-attention-based convolutional neural network with accurate stage division for RUL prediction, which includes two subsections, i.e., First time (FPT) determination estimation. Firstly, signal features characterizing bearing degradation process are fused by Wasserstein Distance to perform robustness. The correct labeled...
Harmonic injection method is widely used in the suppression of current harmonic and torque ripple field-oriented control (FOC) permanent magnet synchronous motor (PMSM) servo system. However, under some working conditions FOC PMSM, fails to suppress harmonics causes oscillation. To analyze cause oscillation, transfer mechanism injected voltage analyzed this article, relation between derived. The theoretical analysis results show that will change with speed parameters PMSM. When reversed,...
Sparse decomposition has been widely used in gear local fault diagnosis due to its outstanding performance feature extraction. The extraction results depend heavily on the similarity between dictionary atoms and signal. However, transient impact signal aroused by defect is usually submerged meshing harmonics noise. It still a challenging task construct high-quality for complex actual To handle this issue, novel method based Empirical Mode Decomposition (EMD) sparse proposed paper. Firstly,...
Frequency components of complicated asymmetric modulation sidebands, existing in the vibration healthy planetary gear train, are prone to be erratically diagnosed as fault characteristics, which leads difficulties diagnosis wind turbine gearbox. The factors affecting sideband, i.e. periodical time‐varying transmission path and meshing force direction, analysed. Considering both vibrations planet–ring planet–sun pairs, a mathematical model was developed analyse train's response. Simulation...
Torque ripple degrades the performance of a permanent magnet synchronous motor (PMSM). Harmonic injection method can minimize torque well by suppressing speed harmonic. But its under transient conditions is not satisfactory. Moreover, too much computation and complex parameter adjustment limit application in multiharmonic suppression speed. Therefore, this article proposes an order-domain-based harmonic (OHI) for multiple harmonics both steady-state conditions. In OHI method, are extracted...
