【摘要】:为了使高超声速飞行器在再入过程中完成姿态控制,在反步法的基础上将模糊自适应和终端滑模控制相结合设计控制器。对于姿态角动态,使用反步法和模糊自适应设计虚拟控制律;而对于角速率动态,利用终端滑模方法设计控制器,能够有效提高系统鲁棒性。稳定性分析说明所提方法可以保证系统状态的一致渐进有界性。
[Abstract]:In order to make the hypersonic vehicle complete attitude control during reentry, the fuzzy adaptive control and terminal sliding mode control are combined to design the controller based on the backstepping method. For attitude angle dynamics, the backstepping method and fuzzy adaptive control law are used to design the virtual control law, while for angular rate dynamics, the terminal sliding mode method is used to design the controller, which can effectively improve the robustness of the system. The stability analysis shows that the proposed method can guarantee the uniform asymptotic boundedness of the system state.
