Time-Varying Group Formation With Adaptive Control for Second-Order Multi-Agent Systems

IEEE Access, 2022
In this study, adaptive time-varying group formation control for second-order multi-agent systems with an undirected topology is studied. First, a conventional multi-group adaptive time-varying formation control protocol is presented, and the stability ...

Theoretical analysis of perching and hovering maneuvers [PDF]

, 2013
Unsteady aerodynamic phenomena are encountered in a large number of modern aerospace and non-aerospace applications. Leading edge vortices (LEVs) are of particular interest because of their large impact on the forces and performance.

Artic-North Atlantic interactions and multidecadal variability of the thermohaline circulation [PDF]

, 2005
Analyses of a 500-yr control integration with the non-flux-adjusted coupled atmosphere–sea ice–ocean model ECHAM5/Max-Planck-Institute Ocean Model (MPI-OM) show pronounced multidecadal fluctuations of the Atlantic overturning circulation and the ...

Controllability of Formations over Time-varying Graphs

, 2014
In this paper, we investigate the controllability of a class of formation control systems. Given a directed graph, we assign an agent to each of its vertices and let the edges of the graph describe the information flow in the system. We relate the strongly connected components of this graph to the reachable set of the formation control system. Moreover,
