A Real-Time Algorithm for Non-Convex Powered Descent Guidance [pdf]

A Real-Time Algorithm for Non-Convex Powered Descent Guidance Taylor P. Reynolds∗, Danylo Malyuta∗, Mehran Mesbahi†, Behçet Açıkmeşe†, Dept. of Aeronautics & Astronautics, University of Washington, Seattle, WA 98195, USA and John M. Carson III‡ NASA Johnson Space Center, Houston, TX 77058, USA The on-board solution of constrained optimal control problems is a key technology for future entry, descent and landing systems. The constraints that must be satisfied to enable advanced navigation routines require powered descent guidance solutions that consider the coupled rotation and translation of the vehicle, leading to a non-convex 6-degree-of-freedom powered descent guidance problem. This paper builds on previous work and refines a successive convexification algorithm to be compatible with common flight code ...
