Robust trajectory tracking algorithms for a wheeled mobile robot

摘要

Control algorithms for a wheeled mobile robot to achieve trajectory tracking are presented. A complete electromechanical model is obtained by incorporating the dynamic models of the actuators in the dynamic equations of a tricycle vehicle. The control scheme has been divided into two levels, namely, path error control and motor control. A method based on the acceleration feedback is applied at a lower level of control. Simulation results are given to illustrate the controller design procedure and the performance of the controller.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
