Unified control solution for mobile robot formations

Abstract

This paper presents a unified control for a formation of mobile robots in positioning, path following, and trajectory tracking tasks. The control is based on a kinematic model of the formation in combination with a dynamic compensator based on a neural sliding mode control to guarantee a good tracking of reference velocities. Stability analysis of the complete system is given by using the Lyapunov theory. Finally, the control scheme is validated through simulations.
