The paper presents a cross-domain fault diagnosis method based on transferred stacked autoencoder, which extracts features from the source domain data to establish a model and then performs domain adaptation with target domain data, demonstrating its effectiveness and superiority through experiments.
In the actual industrial process, the distribution of historical training data and online testing data is always different due to the switching of operating modes and changes in climate conditions. At this time, the performance of traditional data-driven fault diagnosis methods based on the assumption that historical training data and online testing data follow the same distribution will degrade. Therefore, how to ensure the reliability of the fault diagnosis method for the distribution distortion is necessary yet challenge. In this paper, a cross-domain fault diagnosis method based on transferred stacked autoencoder is proposed. In detail, a stacked autoencoder is firstly used to extract features of a large amount of source domain data, and the features are classified to establish the source domain model. Then, a small amount of target domain data is introduced to fine-tune the source domain model to achieve domain adaptation. The effectiveness and superiority of the proposed deep transfer method was demonstrated through wind turbine system experiment and pump truck experiment. In addition, this paper also discusses the number of layers of the stacked autoencoder and model transfer strategies in detail to help practitioners understand the proposed method in practice.
