Leader-following connectivity preservation rendezvous of multi-agent systems based only position measurements

Recently, we investigated the problem of leader-following rendezvous with connectivity preservation for a double integrator multi-agent system subject to external disturbances by a full information feedback control. In this paper, we further study the same problem via the position feedback control only. Additionally, the formulation of the problem in this paper is more general than the previous one in that the disturbances to different followers can be different and these disturbance signals will not be used by the control law. Thus the result of this paper is more practical than that of the previous paper.
