Backstepping based multiple mobile robots formation control

In this paper, we investigate the leader following based formation control of multiple nonholonomic mobile robots. We present a new kinematics model for the leader-follower system using Cartesian coordinates rather than the commonly used polar coordinates in literature. Based on this new model and the idea of integrator backstepping, a globally stable controller is derived for the whole system. Simulation results are included to verify the efficacy of the presented new model and controller.
