This paper studies the tracking control problem of hypersonic vehicle in the process of external disturbance, parameters uncertainties and actuator faults. Firstly, a non-triangular velocity and altitude nonlinear subsystem with mismatched disturbances and actuator faults are established based on the feedback linearization model. Secondly, adaptive dynamic surface fault-tolerant controllers are designed for velocity and altitude subsystems by combining nonlinear filter, adaptive control and back-stepping method. Finally, the Lyapunov stability theory and numercial simulation are carried out to verify the availability of the proposed control strategy.

具有不匹配扰动的超音速飞行器有限时间动态表面容错控制

本文研究了高超声速飞行器在外部扰动，参数不确定性和执行器故障过程中的跟踪控制问题。首先，基于反馈线性化模型，建立了具有不匹配扰动和执行器故障的非三角速度和高度非线性子系统。其次，结合非线性滤波，自适应控制和反步法，为速度和高度子系统设计了自适应动态表面容错控制器。最后，进行了李雅普诺夫稳定性理论和数值模拟，以验证所提出的控制策略的有效性。
