Abstract Details

2007, MS, University of Cincinnati, Engineering : Aerospace Engineering.
The novel concept of multiple spacecraft formation flying as a substitute for a single large vehicle will enhance future space mission performance. The benefits of a spacecraft formation include more cost effective synthetic aperture radar for observations, “graceful degradation” of the formation, flexibility of the satellites altering their roles, reduction of cost owing to the reduction of mass launched into orbit etc. A significant challenge in the domain of control design is to contrive a formation maintenance controller that will enable the member spacecrafts to maintain a desired relative orbit with minimal propellant expenditure. This thesis examines linear and nonlinear LEO formation control methodologies, one of each type, with the aim of evaluating them from a propellant budget, thrust level and error dynamics standpoint. A Linear Quadratic Regulator has been applied on J2-perturbed Clohessy-Wiltshire dynamics. In order to remove the restriction of the applicability of Cartesian local vertical local horrizontal frame based control laws to only circular leader orbits, a sliding mode controller acting on a full nonlinear dynamical model has been implemented.This work also studies the effects of leader orbit eccentricity, inclination and formation radius on formation keeping fuel demand and tracking error. Finally, conclusions are drawn regarding the suitability of the control laws considered and various recommendations made.
