This paper proposes an adaptive antiwindup fault-tolerant control system for a hypersonic vehicle with parametric uncertainties. Not only the loss-of-effectiveness and stuck-type elevator fault, but also the reverse-type fault causing the uncertainty of control direction is considered. The fault-tolerant controller designed through feedback linearization is combined with an online parameter estimator and a Nussbaum gain function, so that the uncertainties can be estimated adaptively. An antiwindup compensator is introduced to the control system to handle the input constraints.

未知控制方向HSV的自适应容错控制

本文提出了一种具有参数不确定性的高超声速飞行器自适应抗饱和容错控制系统。不仅考虑了电梯失效率和卡住型故障，还考虑了导致控制方向不确定的反向型故障。通过反馈线性化设计的容错控制器与在线参数估计器和努斯鲍姆增益函数相结合，可以自适应地估计不确定性。在控制系统中引入了一个抗饱和补偿器来处理输入约束。
