A new control strategy for tracking in mobile robots and AGVs

Abstract

The tracking problem of a wheeled mobile robot or an automated guided vehicle is considered. For the vehicles with a steering wheel, a control strategy is proposed to determine the steering angle at each instant based on measured errors, i.e. the offset from the path and the deviation in orientation. The results of computer simulation of the dynamics of the system and comparisons with other proposed control policies are presented. It is shown that by implementing the new policy significant improvement in tracking capability can be achieved.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
