Profile-tracking guidance of Reusable Launch Vehicle (RLV) is a challenging task due to dramatic aerodynamic data perturbations. A novel adaptive global sliding mode control (AGSMC) scheme is developed so that the closed-loop system shows invariance property to parameter uncertainties all the time. The approach designs a global sliding mode surface based on optimization theory and uses adaptive technology...
A novel method for fast design of reentry drag profile for reusable launch vehicle (RLV) is developed. A reference drag profile as a function of velocity is designed as a two-segment piecewise line subjects to given initial conditions, path constraints, and terminal conditions. The secant method is utilized to search for the turning point of the profile rapidly until the gliding range and the terminal...
