- Abstract:
-
The vibration signals of high-speed electrical-driven bearings under rapidly-varying rotational speed are characterized by stepwise variations in their statistical characteristics, leading to concept drift in the data distribution. Current anomaly detection methods generally rely on static independent and identically distributed (i. i. d.) assumptions, but still struggle to recognize concept drift well, which further results in false alarms. To address these challenges, a concept drift-aware robust anomaly detection method with streaming data is proposed in this paper. First, an anomaly detection pre-training mechanism based on contrastive learning and tensor decomposition is designed to produce high-quality initial features with both generalization and discriminative capability. Second, a new concept drift-aware deep support vector data description (Deep SVDD) model is constructed to enable rapid fine-tuning of streaming data, while calculating the local deviation scores under hyper-sphere constraint. A distribution-aware mechanism using sliding windows and kernel density estimation (KDE) is also integrated to calculate concept drift scores. Finally, these two scores are evaluated together to determine whether the model update under new data distribution is required, with early fault occurrence precisely recognized. Experimental validation on our high-speed bearing testbed under varying operating conditions demonstrates that concept drift points can be accurately filtered out with real early fault identified. The proposed method provides an advance warning of 10 samples compared to the supervisory alarm, while maintaining a zero false alarm rate.
