摘　　要：舰载机的安全着舰是以精确的航迹角控制为前提的,由于着舰环境的复杂性,为航迹角控制提出了更高的要求。针对放宽静稳定性舰载机着舰性能进行研究,采用了一种有效的增稳控制方案,来保证舰载机的稳定性,设计了一种新型二阶滑模控制自动驾驶仪,实现了对俯仰角的精准控制,同时避免了舰尾流扰动的影响及通常滑模控制会导致的控制输入信号抖动现象,并解决了舰载机纵向飞行控制系统对航迹角的稳定性控制问题。仿真结果表明,所设计的控制器可完全满足舰载机着舰过程对抗扰能力和精确跟踪的要求。It is important to accurately control the flight -path angle so as to ensure the aircraft can land on the angle deck of the aircraft carrier safely in the complicated landing environment. The paper studed the landing process of the aircraft with relaxed static design. In order to ensure the aircraft＇s stability, a proper augmented - stability measure was developed. The autopilot that control the pitch angle precisely is designed via second - order sliding mode control, meanwhile, the influence of air disturbance and the chattering phenomena was avoided. So the prob- lem of the longitudinal flight control system to control the flight - path angle can be solved. Simulation results indicate that the controller has perfect abitity of rejection and tracking and fully meet the demand of the carrier - landing.
