This paper presents a novel decentralized control law for the Voronoi-based deployment of a Multi-Agent dynamical system. At each time instant, a bounded convex polyhedral working region is partitioned using a Voronoi algorithm providing the agents with non-overlapping functioning zones. The agents' deployment objective is to drive the entire system into a stable static configuration which corresponds to a stationary maximal coverage.This goal is achieved by using local stabilizing feedback control ensuring the convergence of each agent towards a centroid of its associated functioning zone. The proposed approach considers the Chebyshev center as centroidal point of each Voronoi cell.
