Abstract
This paper presents a flatness and LPV-based methodology for an Apollo-Like Re-entry vehicle (ALRV) guidance. The main contribution is considered to be a proposition which converts the original nonlinear longitudinal ALRV flat model into a fictitious Linear Parameter Varying (LPV) model over which a LPV control law can be designed using a finite set of Linear Matrix Inequalities (LMIs). It is shown that the overall scheme is able to ensure robust stability and robust performances when off-nominal conditions are present. Finally, simulation results are presented to demonstrate the potential of the proposed approach.
