摘　　要：精确的着舰控制以及提高着舰过程的安全性和可靠性是舰载机安全回收的难点问题。提出一种基于增量动态逆的着舰控制系统,采用基于增量动态逆的迎角保持回路与航迹角速率控制回路的方法,实现迎角与航迹的解耦以及直接升力对航迹的直接控制;引入微分跟踪器对增量动态逆控制律中需要的航迹角加速度信号进行估计,通过仿真对着舰控制系统进行验证。结果表明:基于增量动态逆的着舰控制系统具有优异的控制精确性、快速性以及鲁棒性,在不同海况干扰下能够实现对航迹的精确跟踪,并且着舰点满足对舰载机着舰点分布的品质要求。Accurate landing control and improving the safety and reliability of the landing process are difficult issues in the safe recovery of carrier based aircraft.A landing control system based on incremental dynamic inverse is proposed.The method of an angle of attack maintenance loop and a trajectory rate control loop based on incremental dynamic inversion is used,which can achieve decoupling of angle of attack and trajectory,as well as direct control of trajectory by direct lift.A differential tracker is introduced to estimate the track angular acceleration signal required in the incremental dynamic inverse control law.The landing control system is verified with simulation.The results show that the designed landing control system based on incremental dynamic inverse has excellent control accuracy,speed,and robustness.It can achieve accurate tracking of the trajectory under different sea conditions interference,and the landing points can meet the quality requirements for the distribution of carrier based aircraft landing points.
