An adaptive automatic landing guidance control system for fixed-wing unmanned carrier-based aircraft

Abstract

The invention discloses an adaptive automatic carrier landing guide control system of a fixed-wing unmanned carrier-based aircraft. The adaptive automatic carrier landing guide control device comprises a carrier landing instruction and glide reference track generating module, a guide law module and an adaptive flight control module. The carrier landing instruction and glide reference track generating module is used for generating three-dimensional reference glide track signals, speed instruction signals and side slide instruction signals, outputting the three-dimensional glide reference track signals to the guide law module and outputting the speed instruction signals to the adaptive flight control module; the guide law module is used for generating a pitch angle instruction and a roll angle instruction which are two guidance instructions and outputting the two guidance instructions to the adaptive flight control module; the adaptive flight control module is used for generating flight control signals for the unmanned carrier-based aircraft by the aid of multivariable model reference adaptive control algorithms. The adaptive automatic carrier landing guide control system has the advantages that the unmanned carrier-based aircraft can precisely trace glide reference tracks by the aid of the adaptive automatic carrier landing guide control system, and accordingly carrier landing tasks can be successfully accomplished.

Description

technical field [0001] The invention relates to an adaptive automatic landing guidance control system for a fixed-wing unmanned carrier-based aircraft, which belongs to the technical field of aviation vehicle control. Background technique [0002] The "landing" in this patent usually refers to a runway interception landing for a manned carrier-based aircraft, while for an unmanned aerial vehicle, it can include a variety of methods such as runway interception landing and net recovery. [0003] In order to meet the needs of warships such as aircraft carriers, carrier-based aircraft are often used for combat and support activities such as target strikes, air combat, intelligence reconnaissance, and battlefield surveillance. [0004] 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 moveme...

Problems solved by technology

[0008] Third, the controllers of the traditional automatic landing system are all fixed parameter controllers, which lack adaptability to system and environmental changes and external disturbances. They are greatly affected by various uncertainties of the system and environment and external disturbances.

[0009] For unmanned carrier-based aircraft, there is no public report on the technology related to the automatic landing system
