Decentralised event-triggered cooperative control with limited communication

Abstract

This note studies event-triggered control of Multi-Agent Systems (MAS) with first-order integrator dynamics. It extends previous work on event-triggered consensus by considering limited communication capabilities through strict peer-to-peer non-continuous information exchange. The approach provides both a decentralised control law and a decentralised communication policy. Communication events require no global information and are based only on local state errors; agents do not require a global sampling period or synchronous broadcasting as in sampled-data approaches. The proposed decentralised event-triggered control technique guarantees that the inter-event times for each agent are strictly positive. Finally, the ideas in this note are used to consider the practical scenario where agents are able to exchange only quantised measurements of their states.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Theorem 3.1: Given a connected, undirected graph and closed-loop dynamics (30), if event times of each agent i are determined by trigger (33) with 0<a<1/|N_i|, then all non-Zeno trajectories asymptotically achieve multi-agent average consensus.

    “then all nonZeno trajectories of the system asymptotically achieve multi-agent average consensus.”
  • In consensus algorithms, implementing uniform quantizers at each node causes convergence to a bounded region around the initial average rather than asymptotic convergence to the global initial average.

    “In general, an algorithm which would guarantee asymptotic convergence to the global initial average when non-quantized information is transmitted by each agent, is instead only able to converge to a bounded region around the initial average in the case where uniform quantizers are implemented at each node.”
  • With uniform quantizers, the agents' states satisfy lim_{t→∞} ||x_i(t) - x̄|| ≤ c, where c depends on the quantization step size and x̄ is the initial average.

    “The states of the agents satisfy lim t →∞ || x i ( t ) -¯ x || ≤ c , where c is a constant which depends on the size of the quantization step and ¯ x = 1 N ∑ N i =0 x i (0).”

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.
