At present, aircraft are widely used in various fields, including aerial photography, unmanned cargo, and aviation rescue. Hover flight is a common Airplane mode of aircraft. However, in practical operations, the aircraft faces challenges such as unstable hovering attitude, difficult control, and flight safety. In order to improve the hovering flight stability of the aircraft, ensure the attitude stability control effect, and shorten the control tracking response time. A hovering flight attitude stability control method for aircraft based on Internet of Things technology has been proposed. According to actual measurement requirements and standards, represent the flight coordinate system and attitude. Expand the control range using a multi-level mode and deploy multi-level cross control nodes. Establish a hovering attitude stability control model for IoT aircraft, and use adaptive predictive constraints to achieve hovering flight attitude stability control for aircraft. The experimental results show that the final attitude stability control tracking response time of the proposed method is controlled below 0.3 seconds, indicating that the proposed method has good attitude stability control effect for aircraft hovering flight, can effectively shorten the attitude stability control tracking response time, and improve the aircraft’s hovering flight stability.
