AI Technical Summary
⚠Technical Problem
Traditional quadcopter drone control methods are unable to effectively suppress external disturbances such as wind speed and temperature changes, leading to unstable attitude control and reduced flight accuracy.
⚗Method used
A disturbance rejection control method for UAVs based on cascaded EHGO is adopted. By constructing position and attitude observers and introducing a cascaded EHGO controller, the control input is adjusted in real time to compensate for system disturbances and uncertainties.
🎯Benefits of technology
It significantly improves the flight accuracy and attitude stability of quadcopter drones in complex environments, effectively suppresses external interference, and ensures safe landing.

Abstract
This invention relates to a disturbance rejection control method for quadcopter UAVs based on cascaded EHGOs, specifically addressing the challenge of traditional control methods effectively suppressing external disturbances such as wind speed and temperature changes, which lead to unstable attitude control and reduced flight accuracy. This application utilizes a cascaded EHGO design to effectively suppress various disturbances encountered by the quadcopter UAV during flight (such as wind interference and transient disturbances during resting). This mechanism significantly reduces instability caused by changes in the external environment while maintaining flight accuracy, thereby ensuring stable attitude control and improving flight accuracy.
