Formation Control of Wheeled Robots in the Port-Hamiltonian Framework

Abstract This paper proposes a new control strategy for the formation control of a network of wheeled robots. Starting from the rigid body dynamics, a dynamical model of the wheeled robot is derived in the port-Hamiltonian framework. The formation control objective is achieved by interconnecting the robots using virtual couplings, which give a clear physical interpretation of the proposed solution. Simulation and experimental results are given, to illustrate the effectiveness of the approach.
