针对舰尾气流和甲板运动影响着舰精度的问题,提出一种基于自适应动态逆的纵向着舰控制律设计方法。建立舰载机模型、舰尾流和甲板运动模型,基于自适应动态逆控制设计纵向自动驾驶仪,并在Lyapunov稳定意义下证明了控制器的稳定性;设计着舰导引律和迎角恒定的动力补偿器;采用Monte Carlo模拟方法对建立的自动着舰控制系统进行仿真验证。仿真结果表明:该自动着舰控制律具有更好鲁棒性,能够削弱舰尾流和甲板运动的影响,提高了着舰的精度。

Aiming at the problem that the ship wake airflow and deck motion affect the landing accuracy, a longitudinal control law design method based on selfadaptive dynamic inversion is proposed. The longitudinal autopilot is designed based on adaptive dynamic inversion control, and the stability of the controller is proved in the sense of Lyapunov stability;The Monte Carlo simulation method is used to verify the automatic carrier landing control system. Imulation result show that that control law has better robustness, can weaken the influence of ship wake and deck motion, and improve the precision of automatic carry landing.
