摘　　要：针对舰载机人工进场着舰精确轨迹控制中飞行员操纵负担重、着舰环境复杂的问题,提出采用非线性动态逆(NDI)先进控制方法设计基于直接升力的舰载机精确着舰轨迹控制律。首先,综合分析了"魔毯"技术的控制策略,从航迹调整和姿态保持的直接升力解耦控制角度出发,设计了两层NDI回路;然后,采用合理的控制分配方法实现直接升力的舵面分配。仿真结果表明,所提出的精确着舰控制方法能够有效实现"魔毯"式航迹操纵。For the problem of heavy pilot burden and complicated landing environment in manual approach accurate landing trajectory control of carrier aircraft, an advanced NDI control method is proposed to design accurate landing trajectory control law for carrier aircraft based on direct lift. Firstly, the control strategy of "magic carpet" technology is comprehensively analyzed, and a two-layer NDI loop is designed from the perspective of direct lift decoupling control of track adjustment and attitude maintenance. Then, a reasonable control distribution method is used to realize the rudder surface distribution of the direct lift. Simulation results show that the proposed approach can effectively realize "magic carpet" track control.
