Abstract
Since reusable launch vehicles (RLVs) operate in a wide range of flight conditions, the values of the parameters of the dynamic equations are not constant. Therefore, some adaptive control methods for RLVs have been proposed, and digital control systems which are suitable for digital computers. However, the control performance decreases when the nonlinearity strengthens, although linear adaptive control gives an excellent performance when the nonlinearity of the control system can be disregarded. In this article, we apply a digital adaptive feedback linearization control method with time-scale separation to a winged rocket in an abort case. The simulation results show the effectiveness of the control system.
