Abstract :
Trajectory control for a reusable launch vehicle (RLV) is considered in the reentry and launch modes. Decoupling sliding mode controllers are designed to achieve the asymptotic tracking of Euler angles´ profiles upon plant uncertainties and external disturbances. Effectiveness of the sliding mode controllers is confirmed by simulations of trajectory tracking in a trimmed condition for the WB001 RLV studied at NASA Marshall Space Flight Center
