摘　　要：舰载机着舰问题是一个十分复杂的难题。由于航母的斜角甲板只有几十米宽,故而舰载机要降落在航母上需要十分精确的控制。在横测向控制中,最重要的是控制偏心距。为保持期望的着舰姿态,建立了舰载机横侧向着舰的非线性动力学模型,通过设定期望的着舰位置与姿态,将舰载机横侧向动力学模型的状态转化为误差状态,在攻角为11.7°,空速为70m/s的平衡点设计控制器,采用滚动时域预测控制来解决舰载机着舰的横侧向控制问题,用VC++构建三维仿真平台,在MATLAB上建立控制器模型,运用网络通信发送到三维仿真平台上,控制舰载机实现自动着舰。仿真结果表明滚动时域优化算法可以很好的实现舰载机着舰侧回路非线性系统的航迹跟踪与姿态跟踪。A nonlinear kinetic model of aircraft carrier landing in lateral directional axis was established. The states of nonlinear kinetic model were transformed into error states. Receding horizon control was employed to solve the aircraft lateral control problem at the equilibrium point, and the corresponding angle of attack is 11.7~ and air- speed is 40m/s. Exploiting VC ＋ ＋ software constructed 3D simulation environment. The controller was solved with MATLAB and sent to the 3D simulation environment to realize aircraft automatic landing. The simulation results show that receding horizon control can achieve trajectory tracking and attitude tracking of nonlinear aircraft carrier landing system.
