UAV flight control method and system

Abstract

The invention discloses a UAV flight control method and system. The UAV flight control method includes the steps of: setting a flight route, and setting a number of target points on the flight route; controlling the UAV to pass through the the target point. In the present invention, by setting several target points on the flight route, it is equivalent to performing differential processing on the flight route, thereby splitting the entire flight route into several continuous small sections of flight, and finally controlling the UAV to complete the entire flight through all the small sections of the flight Navigation tasks, so as to realize the real-time tracking control of the UAV, reduce the error caused by measurement or external interference, and avoid the deviation from the flight route caused by the error, so that the UAV can travel along the route to the maximum extent. The flight route flight improves the tracking control performance of the UAV and the safety and reliability of automatic navigation.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a flight control method and system for an unmanned aerial vehicle. Background technique [0002] In the existing UAV flight control method, the flight route is usually preset according to the destination, and then the UAV is controlled to fly according to the flight route. However, errors caused by environmental factors such as satellite positioning errors and wind interference during the flight often cause the UAV to deviate from the preset flight route. In the entire flight route, there is only one target point of the UAV, which is the destination, which is the only reference point and is far away from the UAV. The UAV cannot accurately adjust the attitude coordinates according to this reference point, so The UAV that deviates from the flight path cannot be corrected in real time, thus affecting the safety and reliability of UAV navigation.

AI Technical Summary

Problems solved by technology

However, due to errors caused by satellite positioning errors and wind interference and other environmental factors during the flight, the UAV often deviates from the preset flight route.

In the entire flight route, there is only one target point of the UAV, which is the destination, which is the only reference point and is far away from the UAV. The UAV cannot accurately adjust the attitude coordinates according to this reference point, so Unable to correct drones that deviate from the flight path in real time, thus affecting the safety and reliability of drone navigation
