Flight control method and system for unmanned aerial vehicle

Abstract

The invention discloses a flight control method and system for an unmanned aerial vehicle, and solves the problem that the flight stability and the security of the unmanned aerial vehicle cannot be ensured as only one parameter of air speed or ground speed is used for flight control of the unmanned aerial vehicle. The flight control method and system for the unmanned aerial vehicle timely detects the air speed and the ground speed of the unmanned aerial vehicle and timely corrects to obtain the real time true air speed and ground speed of the unmanned aerial vehicle, which reflect the speed of the unmanned aerial vehicle relative to the air in a more real and objective manner. Based on this, the flight control of the unmanned aerial vehicle is carried out with the combination of the real-time real air speed and the real-time real ground speed, so that the flight stability and security can be effectively ensured when the unmanned aerial vehicle is influenced by factors such as turbulence flow, wind shear, crosswind, low level ground effect and the like.

Description

technical field [0001] The invention relates to unmanned aerial vehicle control technology, in particular to an unmanned aerial vehicle flight control method and flight control system. Background technique [0002] Due to factors such as body volume, take-off weight, and overall cost, small and medium-sized UAVs cannot carry multiple sensors like large UAVs, so currently small and medium-sized UAVs only use the parameter of "airspeed" or "ground speed". Control, so that when the drone encounters turbulence, wind shear, crosswind, low-altitude ground effect and other factors, the stability and safety of flight will be reduced, which will affect flight safety. Contents of the invention [0003] In view of the above-mentioned defects existing in the prior art, the present invention provides a UAV flight control method and a flight control system to solve the problem that existing UAVs only use one parameter of "airspeed" or "ground speed" for flight control. , leading to the...
