A Study on Vestibular Illusion of Flying Cadets Based on CSA-ELM Method

Vestibule is one of the sensory organs of pilots for spatial orientation, and vestibular illusion is an important factor affecting flight safety. Therefore, it is of great significance to study the vestibular illusion such as anti- rotation illusion of flying cadets under different rotational speeds and head movements. In this study, through the vestibular function training experiment of flying cadets, the anti-rotation illusion of flying students at 60°/s, 90°/s and 120°/s are simulated. Among them, the steering is divided into forward and reverse, and the ECG characteristic data of participants are obtained in real time. Then, the crow search algorithm (CSA) is combined with the extreme learning machine (ELM) to build the CSA-ELM identification model. Based on CSA-ELM model, the pilot's anti-rotation illusion is identified. The results show that the method is better than other methods in meeting the accuracy requirements. The above shows that the research results in this paper can provide a theoretical basis support for the assessment and evaluation of flight cadet training microscopic behavior.
