| 摘 要： | 应用基于Lyapunov直接法的非线性不确定系统鲁棒控制方法，为某型直升机垂直飞行模态设计了鲁棒控制律，该控制律能保证闭环系统具有全局稳定性。为验证所设计鲁棒控制律的有效性，对直机机垂直飞行的三 机动：设定点悬停、起飞着陆机和忽上忽下机动，分别进行了闭环系统仿真。仿真结果表明，所设计的控制律对系统参数的摄动具有很强的鲁棒性。

| Abstract: | A nonlinear robust controller is constructed for a nonlinear uncertain helicopter system in vertical flight mode using generalized matching conditions (GMC) robust control method based on Lyapunov direct method, and the designed control laws have strong robustness against perturbation to the system parameters. The simulation results are also provided under three traditional vertical maneuvers (spot hover,take off and landing,and up and down). The results show good agreement between the theoretical analysis and simulation results. The designed helicopter can track the given input quickly and stably. |
