Embodiment Construction

[0073] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0074] The principle of the automatic landing control method of carrier-based aircraft based on predictive control is as follows: figure 1As shown, when the ship is traveling on the ocean, the actual measured heave height and sway distance of the deck motion are obtained by the particle filter-based deck motion estimator to obtain the predicted heave height and sway of the deck motion in the next time period distance. The prediction information is input into the landing command and glide reference trajectory generation module to obtain the corrected glide reference trajectory information. Finally, the corrected reference trajectory information is input into the flight controller based on predictive control. This invention can realize the tracking of the glide path trajectory height and side deviation after the carrier-based aircraft enters the glide phase, and real...

Abstract

The invention discloses a control method for automatic landing of a carrier aircraft based on predictive control, and belongs to the technical fields of automatic landing technology, guidance technology and flight control. The invention discloses an automatic landing method for a carrier aircraft based on predictive control by utilizing the known glide slope information and predictable longitudinal deck movement information during the automatic landing process of the carrier aircraft. Among them, the glide slope information is calculated in advance according to the relative position and relative motion relationship between the carrier-based aircraft and the ship, and the deck motion information is estimated by a deck motion estimator based on particle filtering. At the same time, the disturbance of the ship's wake has been considered in the design process of the controller. The invention can ensure the landing accuracy and robustness of the carrier-based aircraft under the interference of deck movement and ship wake during the landing process.

Description

technical field [0001] The invention relates to a control method for automatic landing of a carrier aircraft based on predictive control, and belongs to the technical fields of automatic landing technology, guidance technology and flight control technology. Background technique [0002] The basic principle of the carrier-based aircraft automatic landing control system is that the tracking radar on the aircraft carrier measures the actual position of the carrier-based aircraft, and at the same time, the deck motion sensor measures the motion of the flight deck of the aircraft carrier, and transmits the data to the compensation computer to compensate for the deck motion. , and then calculate the ideal position of the carrier-based aircraft, input the ideal position and actual position of the carrier-based aircraft into the command computer, compare and obtain the error signal, and calculate the control command of the carrier-based aircraft through the guidance control law accor...
