Abstract
This is a classical problem in mathematical physics to describe the dynamics of large-scale multi-agent systems. In this paper, we propose a limit graphon integral-differential system with a weight feature of graphon to represent a large-scale second-order delay multi-agent system, where the time delay represents transmission time lags. We first study the well-posedness, stability, and regularity of the limit system. When the number of agents tends to infinity, we prove that the delay multi-agent system strongly converges to the delay graphon limit system. Then, by utilizing the novel perturbed energy function and delayed matrix exponential estimate methods, we give sufficient conditions for the exponential convergence consensus of the delay graphon limit system. Numerical simulation examples are given to illustrate our results.
