摘　　要：针对考虑攻角约束的高超声速飞行器控制问题,提出一种受限指令滤波器与预设性能方法相结合的反演控制方案。首先,从高超声速飞行器运动模型中划分出高度子系统并基于反演控制方法设计控制器。为了解决攻角约束问题,构造受限指令滤波器对攻角虚拟指令限幅并保证指令的可导性。然后,利用预设性能方法预先设定约束范围,保证攻角跟踪误差始终满足约束条件的同时,提高其瞬态和稳态性能。另外,针对系统参数不确定与外界干扰,采用线性扩张状态观测器(linear extended state observer,LESO)进行观测并补偿。基于Lyapunov稳定理论证明了系统的跟踪误差最终一致有界,最后通过仿真验证了该方法的有效性。For the control problem of hypersonic vehicle with angle of attack(AOA)constraint,a backstepping control scheme combining constrained command filter and prescribed performance method is proposed.Firstly,the altitude subsystem is divided from the hypersonic vehicle motion model and the controller is designed based on the backstepping control method.In order to solve the problem of AOA constraint,a constrained command filter is constructed to limit the virtual command of AOA and ensure the virtual command’s differentiability.Then,the constraint range is set in advance by using the prescribed performance method to ensure that the tracking error of AOA meets the constraint condition and to improve its transient and steady performance.In addition,linear extended state observer(LESO)is used to observe and compensate the parameter uncertainties of the system and external disturbances.Based on Lyapunov stability theory,it is proved that the tracking error of the system is uniformly bounded.Finally,the simulation results show that the proposed method is effectiveness.
