Abstract
In this paper, a novel integrated guidance and control algorithm based
on adaptive high-order sliding mode is proposed for reusable launch
vehicle (RLV) subject to unknown disturbances and actuator faults. We
propose a time-varying barrier function-based adaptive control law to
offset the effects of uncertainties. The remarkable feature of the
developed algorithm is its ability to track the reference commands in
finite time despite unknown disturbances and actuator faults, without
designing the guidance law and attitude controller separately. Finally,
the effectiveness of the proposed algorithm is confirmed by the
simulation results.
