Dynamic Network Design, Identification, and Control

Dynamic Network Topology Design

When a network has limited communication channels, we want to allocate these resources in an optimal way such that the desired network topology has certain global variational properties, i.e., minimal power consumption for information exchange links, or supporting fast convergence of consensus based distributed protocols. In the following demo movie, the UAVs in the star graph converges to the consensus speed much faster than the ones in the chain graph. In the spacecraft formation example, we design the communication ranges between the spacecrafts which result in a time-varying fast convergent networks.

 

Network Establishment for Fractionated Spacecraft

This project examines the proximity network establishment problem among a collection of fractionated spacecraft modules which are initially scattered in space. The objective is to find the optimal trajectory corrections that bring all the space modules into a stable orbit to form a connected network with minimum control efforts.
