Equilibria and steering laws for planar formations

Abstract

Abstract This paper presents a Lie group setting for the problem of control of formations, as a natural outcome of the analysis of a planar two-vehicle formation control law. The vehicle trajectories are described using the planar Frenet–Serret equations of motion, which capture the evolution of both the vehicle position and orientation for unit-speed motion subject to curvature (steering) control. The set of all possible (relative) equilibria for arbitrary G -invariant curvature controls is described (where G = SE (2) is a symmetry group for the control law), and a global convergence result for the two-vehicle control law is proved. An n -vehicle generalization of the two-vehicle control law is also presented, and the corresponding (relative) equilibria for the n -vehicle problem are characterized. Work is on-going to discover stability and convergence results for the n -vehicle problem.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
