This bagging method is feasible and can produce strong economic and social benefits, and is recognized by the majority of fruit farmers. With the frequent occurrence of natural disasters in recent years, search and rescue equipment of four-rotor aircraft has been widely used. Firstly, the overall design architecture of the four-rotor flight system is introduced. Then the dynamic model of the four-axis aircraft is established for the ground coordinate system and the collective coordinate system. At the same time, the response speed, control stability, and robustness are obtained. The control algorithm of aircraft is designed by using sliding mode variable structure control theory. Finally, the simulation data is used to compare the controller with the controller, and it is proved that the controller’s strength and stability meet the requirements of the project.
