Example Embodiment

[0040]Example 2

[0041]A design method for integrated control of ship-based UAV interception and go-around. The specific steps 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 elevator inner loop control strategy to suppress the impact of the ship wake on the landing. , The guidance ring adopts a control strategy based on the sky speed.

[0043]The elevator control is as follows:

[0044]δE=K1Q+K2∫(Q-Qg)dt

[0045]

[0046]

[0047]Where δEElevator control command, Q, QgAre the pitch rate and its command signal,Respectively the sky speed and its command signal, H, HgAre the height signal and its command signal, K1, K2, K3, K4, K5It is the control parameter of the inner and outer loop controller.

[0048]Step 2: Design the control strategy for the ship-touching roll: At this stage, according to the w...

Abstract

The invention belongs to the technical field of aircraft flight control, and particularly relates to an integrated control design method of ship-borne unmanned aerial vehicle arresting landing and escape re-flight. The integrated control design method comprises the steps of S1, designing a control strategy before landing; S2, designing a control strategy of ship-touching sliding; and S3, designinga control strategy of escape re-flight. The integrated control design method mainly solves the problems of arresting landing and escape re-flight of a ship-borne aircraft. An integrated control method is adopted in the longitudinal direction of successful landing and failed landing escape re-flight of the ship-borne unmanned aerial vehicle, other additional judgment conditions are not needed between the two conditions, and the timeliness and safety of escape re-flight when the ship-borne aircraft fails to land are guaranteed.

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...
