Ship-borne unmanned aerial vehicle automatic ship landing control device based on model reference adaptive control

Abstract

The invention discloses a ship-borne unmanned aerial vehicle automatic ship landing control device based on model reference adaptive control, and belongs to the technical field of control of spacecraft instrumentation. The device comprises a ship landing command and gliding reference track generating module and a model reference adaptive flight control module, wherein the ship landing command and gliding reference track generating module is used for generating a three-dimensional gliding reference track signal and a speed command signal according to information of relative positions and absolute positions of a ship and a ship-borne unmanned aerial vehicle; and the model reference adaptive flight control module generates a flight control signal of the ship-borne unmanned aerial vehicle by a model reference adaptive control algorithm, so that an actual flight track and speed tracking ship landing command of the ship-borne unmanned aerial vehicle is the same as a three-dimensional gliding reference track signal and speed command generated by the gliding reference track generating module. The ship-borne unmanned aerial vehicle automatic ship landing control device based on model reference adaptive control is suitable for ship-borne manned aerial vehicles with fixed rings and ship-borne unmanned aerial vehicles with fixed rings. Compared with the prior art, the ship-borne unmanned aerial vehicle automatic ship landing control device based on model reference adaptive control does not need computation of a leading law; and ship landing is controlled accurately, a control system is simple, and control instantaneity is good.

Description

technical field [0001] The invention relates to an automatic landing control device for a ship-borne unmanned aerial vehicle based on model reference adaptive control, and belongs to the technical field of aerospace control. Background technique [0002] The "landing" in the present invention includes landing methods such as runway arrest landing, net collision recovery, etc., and has universality in the principle of the control method. [0003] As an important weapon force of the aircraft carrier, the key technology of carrier-based aircraft is how to ensure safe and accurate landing in a very harsh environment. Due to the harsh landing environment, disturbances such as mothership movement and ship tail airflow will have a great impact on UAV landing, which greatly increases the difficulty of carrier-based aircraft landing and seriously affects the safety of landing. During the sailing process of the ship, due to the influence of waves, sea surges and wind, the hull will p...

Problems solved by technology

However, there is no public application report of the automatic landing system (ACLS) suitable for UAVs

[0005] To sum up, it can be seen that the existing automatic landing control technology for carrier-based aircraft generally has defects such as complex system, poor real-time performance, and high hardware requirements.
