Simulation-to-reality UAV Fault Diagnosis with Deep Learning
This addresses the simulation-to-reality gap for UAV fault diagnosis, enabling cost-effective and safe training, though it appears incremental as it builds on existing domain adaptation techniques.
The paper tackles the problem of poor performance in simulation-to-reality fault diagnosis for quadrotor propellers by proposing a deep learning model with new features and domain adaptation, achieving 96% accuracy in detecting faults.
Accurate diagnosis of propeller faults is crucial for ensuring the safe and efficient operation of quadrotors. Training a fault classifier using simulated data and deploying it on a real quadrotor is a cost-effective and safe approach. However, the simulation-to-reality gap often leads to poor performance of the classifier when applied in real flight. In this work, we propose a deep learning model that addresses this issue by utilizing newly identified features (NIF) as input and utilizing domain adaptation techniques to reduce the simulation-to-reality gap. In addition, we introduce an adjusted simulation model that generates training data that more accurately reflects the behavior of real quadrotors. The experimental results demonstrate that our proposed approach achieves an accuracy of 96\% in detecting propeller faults. To the best of our knowledge, this is the first reliable and efficient method for simulation-to-reality fault diagnosis of quadrotor propellers.
