摘　　要：针对含有不确定性气动参数的吸气式高超声速飞行器(Air-Breathing Hypersonic Vehicles,ABHV)动力学模型,设计自适应Backstepping控制器。Backstepping的设计方法用来补偿模型中的不匹配性不确定性,以保证飞行器跟踪理想的高度、速度、攻角、机体角和俯仰角速率的变化轨迹。利用基于Lyapunov的稳定性分析用来保证控制器状态的渐进稳定性。基于MATALB的数值仿真结果证明设计的控制器的有效性。Aiming at the of air-breathing hypersonic vehicle kinetic model which includes uncertainty of the aerodynamic parameters,this literature design of adaptive Backstepping controller.Backstepping design method was used to compensate the model mismatch uncertainty,in order to ensure the aircraft tracking a desired height,speed,angle of attack,the rate of change of angle and pitch angle of trajectory.Lyapunov stability analysis was used to guarantee the asymptotic stability controller state.MATALB-based numerical simulation results prove that the designed controller is effective.
