With the emergence of large language models (LLMs), artificial intelligence (AI) has experienced revolutionary advancements. Fault diagnosis and maintenance, as crucial components of industrial production, can also undergo significant technological innovations. However, as black-box models, LLMs have three main drawbacks in fault diagnosis scenarios that require deep and responsible reasoning and ...Show More
In real-world applications, the diagnostic efficiency of rolling bearings is commonly affected by operating conditions like fluctuating rotating speed and varying loads, especially, environmental disturbances like transient noises. These disturbances tend to mask the indicators of damage, presenting substantial obstacles for accurately pinpointing failures. Traditional diagnostic methods struggle ...Show More
Health prognostics within the Internet of Things (IoT) paradigm face several challenges, including data privacy, client drift, and prediction accuracy. Federated learning (FL), as an emerging decentralized machine learning paradigm, has the potential to address these challenges by integrating multiple data silos in a distributed and privacy-preserved fashion. This article develops a novel personal...Show More
Deep learning has been widely used for fault diagnosis of complex mechanical equipment in recent years. However, fault types keep increasing with the change in the working state of mechanical equipment in practical scenarios, which causes the performance of traditional machine-learning models to degrade rapidly. Incremental learning can continuously learn new knowledge from incremental information...Show More
Existing health prognostics methods often omit the internal health recovery of proton exchange membrane fuel cells (PEMFCs), although this phenomenon commonly exists, especially in the long-term usage of PEMFCs for hydrogen fuel cell vehicles. To this end, a novel hybrid method for PEMFCs is proposed, and internal recovery effects and external health data are collaboratively leveraged to achieve h...Show More
Online health monitoring of machine tools is an essential technique for tool life extension, manufacturing productivity improvement and product quality improvement. In the era of industrial big data, numerous deep learning (DL)-based methods have been proposed to achieve these goals. However, in complex and dynamic manufacturing processes, practical concerns such as uncertainty quantification and ...Show More
State of health (SOH) is critical to the efficient and reliable use of lithium-ion batteries (LIBs), especially in electric vehicle (EV) applications. Recently, electrochemical impedance spectroscopy (EIS)-based technique has been proven to be effective for SOH estimation of LIB. However, existing EIS-based methods failed to consider the impact of ambient temperature and battery state of charge (S...Show More
Cross-domain fault diagnosis methods based on transfer learning attempt to leverage knowledge from a domain with sufficient labeled samples to a different but related domain with few or even nonlabeled samples. These methods have been widely investigated in the past years. Notwithstanding the efficacy, most existing approaches assume that the label spaces of training and testing data are the same....Show More
The existing deep learning-based fault prognostic methods require massive labeled condition monitoring (CM) data to train a well-generalized model. However, acquiring massive labeled CM data for real-case machines is infeasible due to time, economic costs, and safety concerns. Fortunately, we can handily obtain labeled CM data from relevant but different machines such as from accelerated degradati...Show More
This article develops a generalized deep convolutional neural network (DCNN)-Bootstrap-based prognostic approach for remaining useful life (RUL) prediction of rolling bearing. The proposed architecture includes two main parts: first, a hybrid DCNN model is utilized to simultaneously extract informative representations hidden in both time series-based and image-based features and predict RUL of bea...Show More
This article proposes a novel deep learning based fusion prognostic method for remaining useful life (RUL) prediction of engineering systems. The proposed framework strategically combines the advantages of bidirectional long short-term memory (BLSTM) networks and particle filter (PF) method and meanwhile mitigates their limitations. In the proposed framework, BLSTM networks are applied for further...Show More
In modern industry, engineered systems are generally required to work under complex operational conditions to complete specific missions. But most of existing data-driven prognostic methods still lack an effective model that can utilize operational conditions data to predict remaining useful life (RUL) of engineered systems. To fill these practical gaps, this paper develops a novel prognostic meth...Show More
The effect of path loss on the reliability of wireless communication in Military C4ISR (Command, Control, Communication, computer, Intelligence, Surveillance and Reconnaissance) Architectures has drawn much attention. Previous work were focused on the reliability assessment of infrastructure, but its link reliability has not been fully considered. This paper puts forward a new method for the relia...Show More
