@article {Basiri2010a, title = {Distributed Control of Triangular Formations with Angle-Only Constraints}, abstract = {This paper considers the coupled formation control of three mobile agents moving in the plane. Each agent has only local inter-agent bearing knowledge and is required to maintain a specified angular separation relative to both neighbor agents. Assuming the desired angular separation of each agent relative to the group is feasible, then a triangle is generated. The control law is distributed and accordingly each agent can determine their own control law using only the locally measured bearings. A convergence result is established in this paper which guarantees global asymptotic convergence of the formation to the desired formation shape.}, author = {M. Basiri and Adrian N.
