针对风电叶片在复杂工况下面临的跨域数据分布偏移导致的异常状态评测泛化能力不足问题
提出一种动态域自适应残差注意力网络(DDA-RAN)的跨域异常状态评测方法。该方法融合迁移学习与动态注意力机制
通过双向动态校准策略实现领域偏移协同优化。具体而言
设计动态域自适应注意力残差块(DDAAR-Block)
利用动态域自适应注意力动态调整机制结合可切换式域标识
自适应激活源域或目标域分支
平衡领域共性与特异性特征表征;构建跨域对齐模块
通过梯度截断与门控机制实现分阶段动态训练
促进跨域特征交互与分布对齐;采用自适应多尺度残差块提取深层与浅层时序特征
结合全局自适应池化增强特征鲁棒性;进一步引入正则化多层感知器(MLP)分类器
提升模型泛化能力。实验结果表明
在叶片开裂与覆冰跨域评测任务中
所提方法在目标域准确率(最高达99.36%)、F1分数(99.35%)及马修斯相关系数(MCC)(98.71%)等指标上均显著优于主流对比模型(如对抗判别域适应(ADDA)、域对抗神经网络(DANN))
其中准确率平均提升2.1%~3.8%
可为工业场景下的跨域异常评测提供有益参考。
To address the insufficient generalization ability of abnormal state assessment caused by cross-domain data distribution shifts in wind turbine blades under complex operating conditions
this paper proposes a Dynamic Domain Adaptive Residual Attention Network (DDA-RAN) based cross-domain anomaly assessment method. This approach integrates transfer learning with a dynamic attention mechanism
achieving collaborative optimization of domain shift through a bidirectional dynamic calibration strategy. Specifically
a Dynamic Domain Adaptive Attention Residual Block (DDAAR-Block) is designed. It utilizes a dynamic domain adaptive attention mechanism combined with switchable domain identifiers to adaptively activate either the source or target domain branch
balancing the representation of domain-invariant and domain-specific features. A cross-domain alignment module is constructed
implementing phased dynamic training via gradient truncation and a gating mechanism to promote cross-domain feature interaction and distribution alignment. An adaptive multi-scale residual block is adopted to extract deep and shallow temporal features
enhanced by global adaptive pooling for feature robustness. Furthermore
a regularized Multi-Layer Perceptron (MLP) classifier is introduced to improve model generalization. Experimental results demonstrate that in cross-domain assessment tasks for blade cracking and icing
the proposed method significantly outperforms mainstream comparison models (e.g.
ADDA
DANN) in terms of target domain accuracy (up to 99.36%)
F1-score (99.35%)
and MCC (98.71%). The accuracy shows an average improvement of 2.1%-3.8%. This provides a valuable reference for cross-domain anomaly assessment in industrial scenarios.
