摘要
To address the degradation in diagnostic performance caused by limited gearbox fault samples and variations across variable-speed operating conditions, information fusion-based model-agnostic meta-learning (IFMAML) enables cross-condition few-shot diagnosis by integrating multisensor information fusion with meta-learning, but it insufficiently exploits channel dependencies in deep fused features. IFMAML-ECA, which directly incorporates conventional efficient channel attention (ECA), scales the features using attention weights within the range of (0,1), which may excessively suppress transferable channel responses. To address this issue, this paper proposes an information fusion-based meta-learning method with residual efficient channel attention (ResECA), termed IF-REMAML, which enhances deep fused features through residual channel modulation and adopts an optimization strategy in which the ResECA parameters are fixed during inner-loop adaptation and updated during outer-loop optimization. Multiple cross-condition few-shot diagnostic scenarios are constructed on the Tsinghua University planetary gearbox variable-speed dataset. Experimental results demonstrate that the proposed method achieves favorable cross-condition diagnostic performance and outperforms several representative meta-learning methods.
