Generalized hp Pseudospectral Convex Algorithm for Powered Descent and Landing

摘要

In this paper a generalized hp method is combined with pseudospectral methods andudconvex optimization to provide a high-accuracy, real-time capable method able to computeudoptimal trajectories for planetary powered descent and landing phases of a spacecraft.udThe bene�ts of the method are demonstrated for the Mars Science Laboratory study case.udNumerical simulations show that the method provides a suitable alternative to the standardudconvex approaches, and represents a good trade-o� between accuracy and computationaludspeed.
