Autonomous Distributed Control Algorithm for Multiple Small Spacecraft during Simultaneous Close Proximity Operations
MetadataShow full item record
Development of an autonomous distributed control algorithm for multiple spacecraft in close proximity operations is examined. This research aims to give a contribution to the control of multiple spacecraft for emerging missions, which may require gathering, rendezvous, and docking. A control algorithm is proposed which combines the efficiency ofthe Linear Quadratic Regulator (LQR) and the robust collision avoidance capability of the Artificial Potential Function method(APF). The LQR control effort serves as the attractive force toward goal positions, while the APF-type repulsive functions provide collision avoidance for both fixed and moving obstacles. The multiple spacecraft close proximity control algorithm gave promising results in simulations involving multiple spacecraft maneuvers.
