    Distributed event-triggered flocking control of Lagrangian systems
    (IEEE, 2021-12-20) Aranda Escolástico, Ernesto; Colombo, Leonardo J.; Guinaldo Losada, María
    In this paper, an event-triggered control protocol is developed to investigate flocking control of Lagrangian systems, where event-triggering conditions are proposed to determine when the velocities of the agents are transmitted to their neighbours. In particular, the proposed controller is distributed, since it only depends on the available information of each agent on their own reference frame. In addition, we derive sufficient conditions to avoid Zeno behaviour. Numerical simulations are provided to show the effectiveness of the proposed control law.

    Distributed targeted distance-based formation control for mechanical systems
    (IEEE Xplore, 2020-07-20) Aranda Escolástico, Ernesto; Colombo, Leonardo J.; Guinaldo Losada, María
    This paper studies the problem of distributed targeted distance-based formation control for mechanical systems. The problem consists on finding a distributed control law such that if each agent observes a convex set as a targeted set, and also the relative position of their nearest neighbors, then the agents must achieve the desired formation in these sets while its velocities are driven to zero. We study the problem for agents with a time-delay communication in the measurements of the relative positions and where the motion of each agent is determined by a Lagrangian function. Simulation are given to validate the theoretical result.
