Abstract

The invention belongs to the field of unmanned aerial vehicle control, and particularly relates to an autonomous guidance control system and method for fixed-wing unmanned aerial vehicles on a warship surface. The system comprises an autonomous guidance control display device, an autonomous guidance central processing device, an unmanned aerial vehicle-end airborne wireless communication device and a ship-end ship island wireless communication device. The method comprises a manual guide mode, an autonomous guide mode and a manual correction mode. According to a technical scheme in the invention, the unmanned aerial vehicle can be automatically guided and controlled to be autonomously transferred on a deck according to a gliding path planned by the ship island, meanwhile, deck workers can manually intervene according to deck environment changes or aircraft mechanical response conditions to correct the gliding state of the unmanned aerial vehicle; autonomous, safe and accurate transfer of the ship-borne unmanned aerial vehicles on the warship surface can be achieved through the method; and in addition, with the technical scheme, control effect is good, and a track error is controlled within 0.25 m.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle control, and in particular relates to a fixed-wing unmanned aerial vehicle surface autonomous guidance control system and method. Background technique [0002] With the boarding of medium and large catapult take-off drones, the problem of their transfer on the ship surface also follows. For carrier-based UAVs, although land-based UAVs have realized the function of autonomous entry and exit, due to the limitation of aircraft carrier deck conditions, their guidance accuracy requirements are higher, and it is particularly important to achieve accurate guidance and control of aircraft positioning and orientation. If the ship island directly sends control commands to the UAV, the UAV will transfer autonomously on the deck. Constrained by the deck environment, when an emergency occurs, the island commander cannot grasp the situation immediately and take emergency measures, nor can he correct the ...
