Sliding-mode control for trajectory-tracking of a Wheeled Mobile Robot in presence of uncertainties

Abstract

Wheeled Mobile Robots (WMRs) are the most widely used class of mobile robots. This is due to their fast maneuvering, simple controllers and energy saving characteristics. A dynamics-based sliding mode controller for WMR trajectorytracking is proposed. Robustness to external disturbances and parameter uncertainties is achieved. Closed loop real-time results show good performances in trajectory tracking even if for high upper bound of uncertainties.
