A globally convergent adaptive controller for robot manipulators

Abstract

In this work, a globally convergent adaptive scheme is developed for controlling robot manipulators. Asymptotic behavior of the tracking error is established using the properties of the robot dynamics. A modified version of the controller which employs the filtered torque in its update law is also shown to have the same convergence properties.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
