Center node: "distributed event triggered control for multi agent formation stabilization and tracking"
  Abstract: This paper addresses the problem of formation control and tracking a of desired trajectory by an Euler-Lagrange multi-agent#R##N#systems. It is inspired by recent results by Qingkai et al. and adopts an event-triggered control strategy to reduce the number#R##N#of communications between agents. For that purpose, to evaluate its control input, each agent maintains estimators of the#R##N#states of the other agents. Communication is triggered when the discrepancy between the actual state of an agent and the#R##N#corresponding estimate reaches some threshold. The impact of additive state perturbations on the formation control is studied.#R##N#A condition for the convergence of the multi-agent system to a stable formation is studied. Simulations show the eectiveness#R##N#of the proposed approach.
