An automatic landing guidance method for shipborne UAV

Abstract

The invention discloses an automatic carrier-landing guiding method of a carrier-borne unmanned aircraft and belongs to the technical field of automatic carrier-landing guiding for carrier-borne aircrafts. The method comprises the following steps of determining a reference flight path at a capturing phase according to the initial course information and the positional information of the unmanned aircraft, determining a reference flight path at a tracking phase by considering the influence of deck movement, acquiring a flight-path error at the capturing phase by adopting a direct sightline method, and obtaining a flight-path error at the tracking phase by adopting a dynamic coordinate-system changing method; calculating longitudinal and transverse control-signal instruction values according to the flight-path errors, and guiding the carrier-borne unmanned aircraft to fly along the reference flight paths. The automatic carrier-landing guiding method of the carrier-borne unmanned aircraft provided by the invention has high realizability and operability, so that the carrier-landing performance of the unmanned aircraft under a specific carrier-landing environment is improved; the deck movement is directly led into a carrier-landing tracking-phase guiding algorithm, so that the addition of a deck-movement compensator to a controller is avoided, the complexity of a flight control system is lowered, and the reliability of a carrier-landing system is improved.

Description

technical field [0001] The invention discloses an automatic landing guidance method for a ship-borne unmanned aerial vehicle, which belongs to the technical field of automatic landing guidance for a ship-borne aircraft. Background technique [0002] Due to the broad application prospects of shipborne UAVs in future naval warfare, various naval powers have listed them as one of the important equipment for future large and medium-sized ships. At present, most shipboard UAVs use remote control equipment to ensure stability and controllability during the entire flight phase from takeoff to landing. With the continuous development of science and technology, naval powers require shipboard UAVs to be able to take off and land autonomously / automatically. Therefore, the research on UAV automatic landing technology is particularly important. Landing recovery. Since the research on shipborne UAVs is in its infancy, and due to reasons such as undisclosed technology, there are few publ...

Problems solved by technology

[0004] Conventional guidance algorithms, such as proportional guidance method and deviation elimination method, are almost limited by the dynamic changes of the target area. If the dynamic change prediction is not accurate, the guidance performance will be significantly reduced. In addition, the general intelligent guidance method still has a large amount of calculation. , The disadvantage of slow learning convergence speed, easy to increase the complexity and instability of the system, and poor engineering realization
