“…In comparison to our previous work [18,19], a condition evaluation study on aerospace engines is conducted using weighted Hellinger distance. The dataset for aerospace engines was relatively small while having a larger number of sensors, eliminating the need for feature extraction or similar operations.…”

It is important to improve the accuracy of the levitation system operation assessment, effectively guide the maintenance work of maglev trains, guarantee the safe and stable operation of the maglev system, and avoid the waste of resources. This paper proposes a levitation system condition evaluation method based on weighted Hellinger distance, which can accurately assess the levitation system state. And the feasibility and effectiveness of the algorithm are verified by using levitation system degradation simulation data.
