Abstract

The invention discloses a fixed-wing unmanned aerial vehicle double-aircraft formation team-forming process guidance method. The method comprises the following steps of collecting position and speed information of a lead aircraft and wing aircrafts to construct a relative distance function; if the relative distance function is positive, collecting height and sky-direction speed information of thelead aircraft and the wing aircrafts and course angle information of the wing aircrafts so as to design a rapid tracking guidance instruction for the wing aircrafts; if the relative distance functionis negative, collecting course angle and lateral acceleration information of the lead aircraft and the wing aircrafts to calculate the deviation range of the flight direction and the lateral acceleration of the lead aircraft and the wing aircrafts; if the deviation range exceeds the preset range, acquiring lateral acceleration and roll angle information of the wing aircrafts so as to design a course adjustment guidance instruction for the wing aircrafts; and if the deviation range is within the preset range, collecting the speed and acceleration information of the lead aircraft and the three-dimensional position information of the lead aircraft and the wing aircrafts, and designing a tail end approaching guidance instruction for the wing aircrafts according to the relative positions of thepreset formation patterns of the lead aircraft and the wing aircrafts.

Description

Technical field [0001] The invention relates to the technical field of automatic control, and in particular to a method for guiding a fixed-wing UAV dual-aircraft formation process. Background technique [0002] The key for fixed-wing UAVs to achieve dual-aircraft formation flight is to complete the formation safely, accurately and quickly. During the formation process, the wingman quickly flies from any location to a relatively fixed position from the lead aircraft, and maintains a formation flight with a relative speed difference within a small range from the lead aircraft. During the entire team formation process, the wingman needs to constantly adjust the flight route according to the flight position, speed, route and other status information of the lead aircraft. Therefore, it is difficult for fixed-wing UAVs to quickly complete the safe formation of two-aircraft formation from any state. Summary of the invention [0003] The present invention aims to solve one of the techni...
