摘　　要：面对舰载机人工进场着舰精确航迹控制中飞行员操纵负担重、着舰环境复杂的问题,提出采用两层并联动态逆控制框架设计基于直接升力的精确着舰航迹控制方案,具体采用控制分配处理直接升力面与常规舵面的舵效耦合和多操纵面问题,并从航迹与姿态解耦角度出发,仿真分析了所提的控制框架,证明了它在实现舰载机“魔毯”式精确着舰中的有效性,最后采用全量非线性E-2C涡桨飞机模型仿真验证控制效果可行,满足着舰航迹控制要求。Aiming at the complicated carrier-landing environment and the heavy operating burden of the pilot in manual approach and precision landing control of the carrier aircraft,a two-layer Nonlinear Dynamic Inversion( NDI) control method is used,and Direct Lift Control( DLC) is introduced to achieve trajectory control of the precision carrier landing. Control allocation is applied to deal with multiple control surfaces and decoupling of control surface effects of DLC and conventional surfaces. From the aspects of trajectory and attitude decoupling,simulation analysis is made to the designed control framework,and it is demonstrated that it is effective in achieving the precision carrier landing similar to Magic Carpet. Finally,the E-2 C aircraft model is built and simulated for verification of the designed method. The results show that the control method can perfectly accomplish trajectory control in carrier landing.
