摘　　要：由于飞机与尾流模型的非线性,为实现自动精确着舰,探究了具有尾流抑制能力的非线性控制器设计方法。基于气流扰动影响的飞机六自由度非线性模型,利用非线性动态逆控制方法对各控制回路进行了设计,为抑制尾流扰动,提出了应用非线性观测器进行补偿的方法。仿真结果表明,具有非线性干扰观测器的控制器可以在4 s内使飞机稳定在速度为52.04 m/s,并使航迹角保持在±0.5°变化范围内,最终的着舰侧向偏差为-0.13m。Because of the nonlinearity of aircraft model and the airwake model,this paper studied on the design of nonlinear controller with the airwake rejection ability for carrier landing precisely.6-DOF nonlinear dynamic model of aircraft was delivered considering the influence of the wind.Based on this mode,autonomous carrier landing control law using nonlinear dynamic inverse was designed.For the airwake rejection,the method using nonlinear disturbance observer was proposed.The nonlinear dynamic inverse controller with nonlinear disturbance observer could make aircraft steady at V = 52.04 m / s within 4 s,keeping flight path angle changing in ± 0.5°,and the final lateral landing error was-0.13 m.
