摘要

剩余寿命（Remaining Useful Life

RUL）预测是装备故障预测与健康管理（Prognostics and health management

PHM）技术的关键环节，对于保障装备安全可靠运行和降低维修保障成本具有重要的意义。Mamba是一种基于结构化状态空间序列模型的新兴网络架构，在捕捉时序数据长期依赖关系方面具有显著优势。然而，现有基于Mamba的装备RUL预测方法仍存在卷积核单一固定、局部时序特征捕捉能力不足等问题，限制了模型泛化能力和RUL预测精度的提升。鉴于此，本文提出一种基于多尺度Mamba（Multi-scale Mamba

MsMamba）的RUL预测方法。首先构建MsMamba-GRU并行网络，同时捕捉长期退化趋势与短时动态特征，实现了长短期特征互补提取，突破了单一固定卷积核限制；其次，利用互补特征动态融合（Dynamic Fusion of Complementary Features

DFCF）模块，对提取的长期退化趋势与短时动态特征进行动态融合；最后通过全连接层完成退化特征映射及RUL预测。利用NASA提供的发动机公开数据集对所提出的RUL预测方法进行了验证，实验结果表明，所提方法能够显著提升装备RUL预测的准确性，具有良好的可解释性以及优异的工程应用潜力。

Abstract

Remaining Useful Life (RUL) prediction is a crucial part of Prognostics and Health Management (PHM) technology

and it holds significant importance in ensuring the safe and reliable operation of equipment and reducing maintenance and support costs. Mamba is an emerging network architecture based on a structured state space sequence model

which exhibits significant advantages in capturing long-term dependencies in time-series data. However

the existing RUL prediction methods based on Mamba still face issues such as using a single and fixed convolution kernel

and insufficient ability to capture local temporal features

which limit the model's generalization ability and the improvement of RUL prediction accuracy. In view of this

this paper proposes an RUL prediction method based on Multi-scale Mamba (MsMamba). Firstly

the MsMamba-GRU parallel network is constructed to capture the long-period degradation trend and short-time dynamic features at the same time

so as to realize the complementary extraction of short- and long-period features; secondly

the extracted long-period degradation trend and short-time dynamic features are dynamically fused by the Dynamic Fusion of Complementary Features (DFCF) module; finally

the mapping of degradation features and the prediction of RUL are accomplished through the fully connected layer. The proposed RUL prediction method was validated using NASA's publicly available engine data set. The experimental results show that the proposed method can significantly improve the accuracy of equipment RUL prediction

has good interpretability

and has excellent engineering application potential.
