大机动飞机的非线性鲁棒控制律设计

Nonlinear Robust Control Law Design for a Large Maneuverable Aircraft

采用非线性不确定系统的高增益控制律设计方法，为某型大机动飞机在特定飞行条件下设计了鲁棒控制律，以跟踪期望的输出轨迹，并在不同飞行条件下进行了系统仿真研究。仿真结果表明，采用所设计的控制律，在不同飞行条件下，飞机均可同时完成较精确的纵向和侧向机动跟踪，说明控制律具有较好的鲁棒性。

Using a high gain feedback design method for nonlinear system with uncertainties, a robust control law is designed for a large maneuverable aircraft to track a desire output trajectory. Simulation studies are conducted under different flight conditions,and the results show that using the designed robust control law, aircraft can complete exact longitudinal and lateral maneuvers simultaneously, and the control law has better robustness.
