Special Issue Information

Dear Colleagues,

Condition monitoring and fault diagnosis are essential for ensuring the safety, reliability, and efficiency of modern industrial systems. With the rapid development of sensing technologies, signal processing methods, and intelligent algorithms, data-driven and physics-informed approaches have significantly improved the capability of detecting, diagnosing, and predicting equipment faults under complex operating conditions.

This Special Issue aims to highlight recent advances in theories, methodologies, and practical applications for condition monitoring, anomaly detection, fault diagnosis, and prognostics (e.g., remaining useful life estimation). We welcome innovative research that integrates advanced sensing, efficient algorithms, and real-world validation across diverse industrial scenarios. Contributions that demonstrate robustness, interpretability, and deployability in practical environments are particularly encouraged.

Topics of Interest (non-exhaustive):

  • Signal processing and feature extraction for monitoring data;
  • Machine learning and deep learning for fault detection and diagnosis;
  • Few-shot, one-shot, zero-shot transfer, and self-supervised learning under limited labels;
  • Domain adaptation and robustness to noise, drift, and missing data;
  • Physics-informed and hybrid modeling approaches;
  • Prognostics and health management, including RUL prediction;
  • Multisensor fusion and distributed monitoring systems;
  • Explainable, reliable, and uncertainty-aware diagnosis methods;
  • Benchmarking, datasets, and real-world industrial case studies.

Accurate and reliable train positioning is essential for railway operation control systems. However, conventional extended Kalman filter-based solutions are vulnerable to measurement faults, which can significantly degrade positioning performance. To address this issue, this paper proposes an adaptive maximum correntropy robust filter (AMCRF) for a GNSS/INS-based train positioning system. The loss function of the extended Kalman filter is reformulated from the minimum mean square error criterion to a maximumcorrentropy criterion, thereby improving the algorithm’s robustness against measurement faults. In AMCRF, considering the limitation of using a fixed kernel bandwidth, a lion swarm optimization strategy is introduced to adaptively tune the kernel bandwidth for each visible satellite, enabling the filter to adapt to time-varying measurement quality and fault magnitudes. By embedding the adaptive mechanism into an extended Kalman filtering framework, the proposed method achieves enhanced fault tolerance. The effectiveness of the proposed AMCRF is validated using experimental data collected along the Qinghai–Tibet Railway. Step and ramp faults of different magnitudes are injected into pseudorange measurements to evaluate fault tolerance. Experimental results demonstrate that the proposed method effectively suppresses the influence of faulty measurements and maintains positioning accuracy close to that under fault-free conditions.
