Multi-AUV Control and Adaptive Sampling in Monterey Bay

IEEE Journal of Oceanic Engineering, 2004
Multi-AUV operations have much to offer a variety of underwater applications. With sensors to measure the environment and coordination that is appropriate to critical spatial and temporal scales, the group can perform important tasks such as adaptive ocean sampling. We describe a methodology for cooperative control of multiple vehicles based on virtual

Convergence Analysis on Multi-AUV Systems With Leader-Follower Architecture

IEEE Access, 2017
In multi-autonomous underwater vehicle (multi-AUV) systems, the convergence rate is characterized by the pace of consistency of the key state information for each member. The topology with leader-follower architecture is designed as a combination of an undirected graph between followers and a digraph between leaders and followers.
