摘要

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.
