Abstract
A model predictive static programming (MPSP) guidance is presented in this paper for a carrier launch vehicle propelled by solid motor in a hypersonic technology demonstrator mission. The nonlinear suboptimal guidance assures very stringent final conditions at the injection point at the end of the guidance phase for successful beginning of the hypersonic vehicle operation. The recently-developedMPSP technique has been extended in this paper with flexible final time to ensure the very stringent final conditions with limited number of iterations. The technique is also further extended to incorporate input constraints, which ensures that the angle of attack and structural load bounds are not violated throughout the trajectory. A second-order autopilot has been incorporated in the simulation studies to mimic the effect of the inner-loops on the guidance performance. Simulation studies indicate that the proposed MPSP guidance can meet the stringent requirements of the hypersonic mission. Extensive simulation studies with perturbations in the thrust-time behavior, drag coefficient and mass demonstrates that the proposed algorithm is robust to modeling inaccuracies as well.
