Abstract

The problem of stabilizing a spacecraft on Circular Restricted Three Body Problem orbits with a nonlinear, feedback controller subject to input constraints is studied in this paper. The proposed solutions are based on Lyapunov methods, which are fused with results from convex optimization. The control inputs are calculated online, through a pointwise Quadratic Programming optimization problem, while the neighborhood around the orbit where stabilization is possible is calculated offline, using Semidefinite Programming techniques with sum of squares constraints. The results can be used for the design and execution of low thrust spacecraft missions in multi-body environments.
