Multi-step self-guided pathways for shape-changing metamaterials [PDF]

, 2018
Multi-step pathways, constituted of a sequence of reconfigurations, are central to a wide variety of natural and man-made systems. Such pathways autonomously execute in self-guided processes such as protein folding and self-assembly, but require external

Spacecraft Formation Reconfiguration using Impulsive Control Input [PDF]

International Journal of Aeronautical and Space Sciences, 2013
This paper presents formation reconfiguration using impulsive control input for spacecraft formation flying. Spacecraft in a formation should change the formation size and/or geometry according to the mission requirements and space environment. To modify the formation radius and geometry with respect to the leader spacecraft, the follower spacecraft ...
