Convolution-Graph Attention Network With Sensor Embeddings for Remaining Useful Life Prediction of Turbofan Engines

IEEE Sensors Journal, 2023
The remaining useful life (RUL) prediction of turbofan engines is beneficial to safe operation and maintenance. Turbofan engines generally require multisensors to monitor the operational state, but current mainstream RUL prediction models tend to ignore ...

Practical Anti-windup for Open-Loop Stable Systems Under Magnitude and Rate Constraints: Application to Turbofan Engines

IEEE transactions on industrial electronics (1982. Print), 2023
In this study, a practical anti-windup algorithm based on the state-space model (AWSS) is proposed to solve the performance deterioration problem for open-loop stable systems under actuator magnitude and rate constraints.

Digital Twins-Based Online Monitoring of TFE-731 Turbofan Engine Using Fast Orthogonal Search

IEEE Systems Journal, 2022
Due to the complicated structure of the aircraft engine, it is hard to observe the damage and determine its status with the traditional diagnosis method, which sets a fixed threshold for some specific parameters.
