Abstract: The embodiments is an unmanned aerial vehicle. The unmanned aerial vehicle includes: an airframe; and a fixed-wing assembly and a rotor assembly, both replaceably connected to the airframe. The fixed-wing assembly is connected to the airframe to form a vertical take-off and landing fixed-wing unmanned aerial vehicle and the rotor assembly is connected to the airframe to form a multi-rotor unmanned aerial vehicle, thereby implementing an unmanned aerial vehicle that can switch between the vertical take-off and landing fixed-wing unmanned aerial vehicle and the multi-rotor unmanned aerial vehicle.

Abstract: Embodiments of the present invention relate to the field of aerial photography technologies and disclose an aircraft control method and an aircraft. The aircraft control method is applicable to the aircraft, and the aircraft includes a flight control system (FCS) configured to control the aircraft and a gimbal control system (GCS) configured to control a gimbal. The GCS can obtain a yaw control instruction to be inputted into the aircraft and attitude angle information outputted by the gimbal and then control yawing of the gimbal according to the yaw control instruction to be inputted into the aircraft and the attitude angle information outputted by the gimbal, so as to implement high-precision control of aerial photography of the aircraft, thereby ensuring high quality of an aerial video and resolving video freezing during aerial photography at a low rotation speed.

Abstract: The present invention discloses an unmanned aerial vehicle and a method for controlling a gimbal thereof. The method for controlling a gimbal includes: generating, by a flight control system, a yaw angular speed instruction of the unmanned aerial vehicle; and controlling, by a gimbal control system, a yaw axis motor of the gimbal according to the yaw angular speed instruction of the unmanned aerial vehicle. In the present invention, the yaw axis motor of the gimbal is jointly controlled by the flight control system and the gimbal control system, so that advantages of high-precision control and quick response of the gimbal control system are maximized. The advantages are used for compensating for deficiencies of the flight control system in yaw control, thereby improving the stability of a yaw channel of the gimbal, and completely resolving frame freezing of an aerial video when the unmanned aerial vehicle yaws at a low speed.
