  In this paper, we propose a method to control large-scale multiagent systems
swarming in a ring. Specifically, we use a continuification-based approach that
transforms the microscopic, agent-level description of the system dynamics into
a macroscopic, continuum-level representation, which we employ to synthesize a
control action towards a desired distribution of the agents. The
continuum-level control action is then discretized at the agent-level in order
to practically implement it. To confirm the effectiveness and the robustness of
the proposed approach, we complement theoretical derivations with a series of
numerical simulations.
