Emergence of flocking for a multi-agent system moving with constant speed
Sun-Ho Choi, Seung‐Yeal Ha · Communications in Mathematical Sciences · 2016
We present a Cucker-Smale-type flocking model for interacting multi-agents(or particles) moving with constant speed in arbitrary dimensions, and derive a sufficient condition for the asymptotic flocking in terms of spatial and velocity diameters, coupling strength and a communication weight.In literature, several Vicsek-type models with a unit speed constraint have been proposed in the modeling of self-organization and planar models were extensively studied via the dynamics of the heading angle.Our proposed model has a velocity coupling that is orthogonal to the velocity of the test agent to ensure the constancy of speed of the test agent along the dynamic process.For a flocking estimate, we derive a system of dissipative differential inequalities for spatial and velocity diameters, and we also employ a robust Lyapunov functional approach.
