Embodiment 2

[0041] An integrated control design method for a shipborne unmanned aerial vehicle to arrest a ship and escape and go around, the specific steps of which include:

[0042] Step 1: Design the control strategy before landing: the control strategy of the longitudinal elevator control channel continues the control strategy of the air section, and the control strategy based on the pitch angle rate is adopted in the control strategy of the inner ring of the elevator. In order to suppress the influence of the ship wake on the ship landing , the guidance ring adopts the control strategy based on the skyward velocity.

[0043] The elevator controls are as follows:

[0044] δ E =K 1 Q+K 2 ∫(Q-Q g )dt

[0045]

[0046]

[0047] where δ E is the elevator control command, Q, Q g are the pitch rate and its command signal, respectively, Respectively, the sky direction speed and its command signal, H, H g are the height signal and its command signal respectively, K 1 、K 2 、K...

Abstract

This application belongs to the technical field of aircraft flight control, and in particular relates to an integrated control design method for ship-borne unmanned aerial vehicles to arrest landing and escape and go around, which includes step 1: designing the control strategy before landing; Run control strategy: Step 3: Design escape and go-around control strategies; this method mainly solves the problem of carrier-based aircraft intercepting landing and escaping and go-around. The integrated control method does not require additional judgment conditions between the two situations, ensuring the timeliness and safety of escape and go-around when the carrier-based aircraft fails to land on the ship.

Description

technical field [0001] The present application belongs to the technical field of aircraft flight control, and in particular relates to an integrated control design method for a carrier-borne unmanned aerial vehicle to arrest a landing and escape a go-around. Background technique [0002] The United States is currently at the forefront of the world in research on carrier-based UAV landing technology. The carrier-based UAV X47-B it developed successfully landed on the USS George Bush aircraft carrier on July 10, 2013. Domestic research on carrier-based aircraft mostly focuses on the control technology of manned carrier-based aircraft, and most of the research focuses on the direction of trajectory tracking. Whether the manned carrier-based aircraft is successfully intercepted or not depends mainly on the judgment of the pilot. The research on carrier-based UAV landing is basically blank in China. Therefore, the research on the terminal landing and go-around escape of carrier-b...
