Autonomous control method for fixed point landing of shipboard unmanned aerial vehicle

Abstract

Disclosed is an autonomous control method for fixed point landing of shipboard unmanned aerial vehicles. The autonomous control method is characterized in that the autonomous control method comprisesa control method of a height guiding section, a control method of a two-dimensional guiding section, and a control method of a tail end guiding section; a shipborne unmanned aerial vehicle firstly enters the height guiding section, tracks the sliding trajectory through the control method of the height guiding section, and carries out trajectory coarse adjustment during the whole landing process; the shipborne unmanned aerial vehicle enters the two-dimensional guiding section at the height of 200 m relative to the airport, and realizes accurate track of the trajectory through the control methodof the two-dimensional guiding section; and the shipborne unmanned aerial vehicle enters the tail end guiding section at the height of 15 m relative to the airport, and realizes that the nose of theunmanned aerial vehicle is aligned with the runway center line during landing of the unmanned aerial vehicle through the control method of the tail end guiding section. According to the autonomous control method for fixed point landing of shipboard unmanned aerial vehicle, the smooth transition of the shipboard unmanned aerial vehicle from the approach flat flying section to the sliding is realized; accurate track of the sliding trajectory line in the sliding process of the shipborne unmanned aerial vehicle is realized, the effect that the nose of the shipborne unmanned aerial vehicle is aligned with the runway center line during landing of the unmanned aerial vehicle is realized; and the precision of fixed point landing of the unmanned aerial vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aviation flight control, in particular to an autonomous control method applied to fixed-point landing of a carrier-borne unmanned aerial vehicle. Background technique [0002] Compared with fixed-point landing of manned carrier-based aircraft, unmanned carrier-based aircraft has the advantages of high intelligence, safety and reliability, not limited by environmental factors, and no casualties. [0003] The land-based fixed-point landing test of the unmanned carrier-based aircraft not only ensures the safety of the carrier-based UAV system, but also provides technical reserves and support for the carrier-based UAV to intercept and land on the ship. Fixed-point landing is different from conventional landing. Conventional landing does not have high requirements on the accuracy of the landing point, and the UAV is controlled to "float" at a lower lifting speed when landing; while fixed-point landing has high...
