中文摘要：
高超声速飞行器在飞行过程中超燃冲压发动机对攻角及侧滑角有较严格的要求，为实现对攻角及侧滑角的精确控制，本文采用自抗扰控制技术设计高超声速飞行器的攻角自动驾驶仪；采用扩张状态观测器对受扰对象的状态和干扰进行观测，并对状态误差采用非线性反馈，对观测的干扰进行补偿，从而实现对干扰的抑制和对指令的精确跟踪，最后仿真实验表明所设计的自动驾驶仪满足性能要求，验证了该方法的正确性。
英文摘要：
Hypersonic vehicle requires strictly for angle of attack and angle of sideslip when its engine is working. To meet the requirements, angle of attack autopilot is designed with auto-disturbance rejection control. The system＇ s state and the disturbance are estimated using the extended state observer. The state error is feedbacked nonlinearly and the disturbance is compensated in order to trace the dictates accurately. With the result of the simulation, it is shown that this method of control can reject the disturbance and meets the requirements well.
