Bevilacqua, R., Lehmann, T., Romano, M., 
"Development and Experimentation of LQR/APF Guidance and Control for 
Autonomous Proximity Maneuvers of Multiple Spacecraft", 
accepted for publication on the Elsevier Acta Astronautica. To appear.

The modifications to the controller resolve issues related to local minima, 
so that the spacecraft can complete tasks, even encountering symmetric configurations.
