中文摘要：

文章针对高超声速飞行器在缺少实际试飞数据的情况下,需要设计鲁棒自动驾驶仪的舵回路控制器来保证飞行器的姿态角控制精度满足超燃冲压发动机的工作条件。根据高超声速飞行器横滚通道的动态特性,针对舵回路的死区间隙等非线性不确定性因素,结合滚动通道数学模型,采用Lyapunov方法设计了横滚通道差动舵的鲁棒控制器。其鲁棒控制律对系统参数不确定性和外界干扰不确定性的补偿控制采用差动舵偏补偿算法,自动补偿不确定因素及舵回路死区、饱和的非线性影响,并完成了其鲁棒指数镇定的证明。最后通过数字仿真验证了文中控制算法的有效性。

英文摘要：

Aim.Ref.1 points out that the effect of nonlinear dynamics of dead zone and the backlash of rudder on the robustness of HV needs to be studied.To our knowledge,there is as yet no paper in the open literature on such study.Section 2 of the full paper designs the robust controller for the roll channel with the Lyapunov theory.Subsection 2.1 gives eq.(2) to establish the model for calculating the effect on control uncertainty of the dead zone. Subsection 2.2 designs the robust controller by using eq.(10) to ca...
