Smooth transition method for flight altitude control of unmanned aerial vehicles

Abstract

A smooth transition method for UAV track flight altitude control, involving the field of UAV control, solves the problem of using only height information for altitude control during the course of UAV track flight, and the UAV will use the maximum The ability to climb leads to the problem of large overload and reduced flight safety of the UAV. The method includes the following steps: receiving the flight waypoint information, flight speed and current position of the drone; calculating the height difference between the front and rear two track points and the straight-line distance in the horizontal direction according to the waypoint information at both ends of the current track. ;Based on the above information, the altitude given value is calculated using the natural exponential law; the altitude given value calculated in real time is input to the altitude control system, so as to realize the smooth transition of altitude control. The present invention gives the altitude command in real time according to the track point information according to the law of the natural index, which can reduce the short-term large overload during the flight altitude control process of the drone track, and improve the flight safety of the drone.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle control, in particular to a smooth transition method for controlling the flight height of the unmanned aerial vehicle track. Background technique [0002] In the altitude control of UAV track flight, in the process of flying from the current point to the target waypoint, if only the altitude information is used, the altitude control law will make the UAV climb with the maximum capacity to reach the target waypoint as soon as possible. Altitude, regardless of the actual distance of the target waypoint from the current point. In this case, in the initial stage of transition, since the UAV climbs at its maximum capacity, the UAV will be overloaded, which is not conducive to flight safety and is prone to safety accidents. At present, there is no report on a similar smooth transition method in the altitude control of UAV track flight. Contents of the invention [0003] In order to s...

Problems solved by technology

[0003] In order to solve the problem that only the altitude information is used for altitude control during the flight of the UAV track, but the UAV will climb with the maximum capacity in the early transition period, resulting in a large overload of the UAV and a decrease in flight safety. The present invention provides a Smooth transition method for flight altitude control of unmanned aerial vehicles
