Problems solved by technology
[0003] During the operation of agricultural unmanned aerial vehicles, the pesticides, seeds or water loaded on them are continuously reduced with the operation time, that is, the load quality of agricultural unmanned aerial vehicles is constantly changing, but the current control method for agricultural unmanned aerial vehicles is still fixed according to the load. The control strategy is used to control, resulting in poor flight stability of agricultural unmanned aerial vehicles during operation

An embodiment of the invention provides a control method of an agricultural unmanned aerial vehicle, a flight controller and an agricultural unmanned aerial vehicle. The control method comprises the steps of acquiring mass of the agricultural unmanned aerial vehicle, wherein the mass of the agricultural unmanned aerial vehicle comprises mass of an agricultural unmanned aerial vehicle body and massof a load; according to the mass of the agricultural unmanned aerial vehicle, adjusting the flight parameter of the agricultural unmanned aerial vehicle; and according to the flight parameter, makingthe agricultural unmanned aerial vehicle fly. According to the embodiment of the invention, through acquiring the mass of the agricultural unmanned aerial vehicle, the flight parameter is adjusted according to the mass of the agricultural unmanned aerial vehicle, and furthermore flight of the agricultural unmanned aerial vehicle is controlled according to the flight parameter. Because the mass ofthe load of the agricultural unmanned aerial vehicle changes in real time, the mass of the agricultural unmanned aerial vehicle changes in real time, thereby realizing real-time adjustment of the flight parameter according to the continuously changing mass of the agricultural unmanned aerial vehicle, ensuring smooth flight and realizing uniform spraying of loaded pesticide, seeds, water and the like.
Description
technical field [0001] The embodiments of the present invention relate to the field of unmanned aerial vehicles, and in particular to a control method for an agricultural unmanned aerial vehicle, a flight controller, and an agricultural unmanned aerial vehicle. Background technique [0002] Agricultural unmanned aerial vehicles need to complete agricultural and forestry plant protection operations, so the requirements for agricultural unmanned aerial vehicles are higher, such as controlling the spraying flow of pesticides, controlling agricultural unmanned aerial vehicles to fly along the route, and controlling the direction of spraying pesticides from sprinklers. [0003] During the operation of agricultural unmanned aerial vehicles, the pesticides, seeds or water loaded on them are continuously reduced with the operation time, that is, the load quality of agricultural unmanned aerial vehicles is constantly changing, but the current control method for agricultural unmanned a...
