Return control method, flight control device and drone

Abstract

The invention discloses a return control method, a flight control device and a drone, which are beneficial to improving the return performance of a drone. The drone has a fixed-wing flight mode and arotor flight mode, and the method comprises: if a drone satisfies a return condition, acquiring a current flight mode of a drone, a flight height of a drone, and a horizontal distance between a droneand a return position (S201); determining a homeward voyage strategy according to the flight mode, the horizontal distance and the flight height (S202); and controlling the drone to return according to the return strategy (S203).

Description

technical field [0001] The present application relates to the field of control technology, in particular to a return control method, a flight control device and an unmanned aerial vehicle. Background technique [0002] Automatic return is one of the common functions in the UAV flight control system. Its purpose is to control the UAV to automatically return from any position to the return position set by the user (ie, the home point). In practical applications, the existing UAV automatic return functions are designed solely for rotary-wing UAVs or fixed-wing UAVs. For UAVs with both rotor flight mode and fixed-wing flight mode, the respective advantages of the two flight modes are not fully utilized, so they cannot achieve better performance in terms of return time and return energy consumption. Contents of the invention [0003] The application discloses a return flight control method, a flight control device and an unmanned aerial vehicle, which are beneficial to improvi...
