Two-layer virtual leader-following: An adaptive cooperative path following control for crowded UUV swarm subjected to constraints

Hongtao Liang et al.

Summary: This paper investigates the adaptive cooperative path following problem of a crowded UUV swarm in the presence of constraints. A two-layer virtual leader-following system is developed to satisfy the requirements of traffic flow, connectivity, and collision avoidance. The consensus algorithm is used to estimate the center of mass, and a new guidance method and controller with a finite-time sideslip-angle observer are designed to improve path tracking performance.
