舰载无人机着舰纵向控制律设计

Longitudinal Control Law Design of Carrier UAV During Carrier Landing

针对舰载无人机着舰末端纵向通道存在姿态与轨迹耦合的问题,提出了一种采用升降舵通道控制姿态、发动机通道控制轨迹的解耦控制策略;应用动态逆与自适应相结合的控制方法,削弱了控制系统中未知扰动带来的影响,保证了控制系统的快速性。为减小着舰末端甲板运动对着舰误差的影响,设计了甲板运动补偿网络。仿真结果显示,该控制方案控制效果良好,控制器具备较强的抗扰能力,可以有效减小舰尾气流对无人机着舰的影响。

In order to solve the problem in carrier UAVs of the coupling of attitude and trajectory in the longitudinal channel at the end of carrier landing,a decoupling control strategy was proposed by using the elevator channel to control the attitude and using the engine channel to control the trajectory.The control method made up of dynamic inversion and adaptive control was applied to weaken the influence of unknown disturbances and guarantee the rapidity of the control system.In order to reduce the landing error caused by deck motion,the deck motion compensation network was designed.The simulation results show that the control scheme has a satisfactory control effect,and the controller has strong anti-interference ability,which can effectively reduce the influence of the ship stern flow.
