Abstract This paper investigates the finite-time H∞ adaptive control of linear systems with unknown mismatched uncertainties. To deal with outage and stuck failures on the actuator and the uncertainties, a new finite-time adaptive H∞ control strategy is proposed. With the established strategy, the resultant closed-loop system is finite-time bounded with the required H∞ level. The validity of the proposed method is demonstrated by an existing rocket fairing model.

致动器失效的未知不确定系统的H∞有限时间控制

摘要 本文研究了具有未知失配不确定性的线性系统的有限时间H∞自适应控制。针对执行器断电、卡滞故障和不确定性问题，提出了一种新的有限时间自适应H∞控制策略。使用既定的策略，合成的闭环系统是有限时间的，具有所需的 H∞ 水平。现有的火箭整流罩模型证明了所提出方法的有效性。
