Embodiment 1

[0060] Embodiment 1, a method for improving the flight performance of UAV route based on fitting wind resistance model:

[0061] S1, in a windless environment, collect the attitude of the drone at different speeds: in a windless situation (such as in an indoor environment), the drone is moving in the air, and the speed of the drone relative to the air is V, Then the speed of the air relative to the drone is -V; the drone overcomes the wind resistance through a certain posture, and finally reaches a balance. This relationship between posture and speed is related to the air density, the shape of the body, the weight of the body, the centroid of the body, etc.; but it will be a relatively balanced relationship.

[0062] Specifically, when there is no wind, put the UAV in the straight-line route mode (curved route mode is not feasible), keep the altitude constant, and set different straight-line route speeds: 1m / s, 2m / s, 3m / s . Angle (pitch angle); attitude angle (pitch angle) i...

Abstract

The invention discloses an unmanned aerial vehicle and a method for improving the flight performance of the unmanned aerial vehicle route, which belongs to the technical field of unmanned aerial vehicles. The key points of the design are: S1, in a windless environment, to collect the attitude of the unmanned aerial vehicle at different speeds ; S2, establish the speed-attitude correspondence of the UAV; S3, feed forward the attitude to the control system. The present invention aims to provide an unmanned aerial vehicle and a method for improving the route flight performance of the unmanned aerial vehicle, which can bring smaller attitude jitter and faster attitude convergence time during route flight.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicles, and more specifically, relates to an unmanned aerial vehicle and a method for improving flight performance of an unmanned aerial vehicle route. Background technique [0002] For unmanned aerial vehicles (gyroplanes), the flight control system is its core component. Specifically, it includes three major systems: guidance, control, and navigation: the guidance system generates control commands; the navigation system calculates the motion of the unmanned aerial vehicle in real time. Status; the control system integrates the information of the guidance and navigation system, and generates instructions for the motor according to a certain algorithm to complete various tasks. [0003] When UAVs perform missions, it is often necessary to plan route tasks in advance. The biggest influence of UAVs on the route is the influence of airspeed: UAV flight speed, wind speed, wind type (tailwind, ...
