针对无人机自动着舰,运用总能量控制(TECS)的思想建立了无人机自动着舰系统,设计了H∞输出反馈控制器,H∞控制综合设计采用包括增量线性化动力学模型、反馈控制器和权阵系数选择的增广对象模型。为了实现对移动目标的跟踪,引入了一种新的着舰导引控制算法。通过对所设计的"先锋"无人机自动着舰导引系统仿真表明,该设计能满足着舰要求,能有效地抑制风干扰的影响,具有良好的鲁棒性能。

Focused on automatic carrier landing for unmanned aerial vehicle, total energy control technique is employed to develop automatic carrier landing system. H∞ control theory is used to the design of the carrier landing system. The resulting H∞ output feedback controller is presented, the increment linear kinetic model, feedback controller and enhanced object model for selecting weight array coefficient are applied in synthesis design of H-infinity control. To achieve the track capability to a moving target, a new guidance control algorithm is introduced. The automatic landing system of a UAV is simulated, and the simulation result shows that it can meet the requirements of carrier langing, and can restrain wind disturbance. The design has the excellent robustness performance.
