AI Technical Summary
The electric push rod control method of the existing drone door opening and closing mechanism has an open-loop control mode with fixed output force and speed. It does not take into account the influence of load changes and external wind disturbances, resulting in opening and closing jamming and excessive structural impact under heavy load or strong wind conditions. In addition, it lacks a closed-loop dynamic adjustment mechanism throughout the process, and cannot achieve smooth movement and precise stopping.
A collaborative control model for the push rod output force, opening and closing speed, and hatch attitude is established. The opening and closing angle, load status, and environmental wind disturbance data are collected in real time. The optimal driving parameters are dynamically calculated, and a closed-loop control mode is adopted throughout the process to continuously adjust the output force and speed of the electric push rod, so as to achieve smooth movement and precise stopping of the hatch.
It effectively avoids structural impact and jamming during the opening and closing process, significantly improves the door positioning accuracy, extends the service life of the opening and closing mechanism, and is easy to deploy in batches on existing logistics drone platforms.
