This paper investigates the design problem of the attitude controller for air-breathing supersonic vehicle subject to uncertainties and disturbances. Firstly, the longitudinal model is established for the attitude controller design which is devised as a strict feedback formulation, and a transformed tracking error is derived with the prescribed performance control technique such that it can limit the tracking error to a predefined region. Then, a novel linear active disturbance rejection control scheme is proposed for the attitude system to enhance the steady-state and transient-state performances by incorporating the transformed tracking error. On the basis of the Lyapunov stability theorem, the convergence and stability characteristics are both rigorously proved for the closed-loop system. Finally, extensive contrast simulations are conducted to demonstrate the effectiveness, robustness, and advantage of the proposed control strategy.

具有规定性能的超音速飞行器姿态系统的线性主动干扰抑制控制设计

本文研究了具有不确定性和干扰性的呼吸超声速飞行器姿态控制器的设计问题。首先，建立用于姿态控制器设计的纵向模型，该模型被设计为严格的反馈公式，并使用规定的性能控制技术导出变换后的跟踪误差，从而可以将跟踪误差限制在预定范围内。然后，针对姿态系统提出了一种新的线性主动干扰抑制控制方案，通过结合变换后的跟踪误差来提高稳态和瞬态性能。基于Lyapunov稳定性定理，严格证明了闭环系统的收敛性和稳定性。最后，
