Hybrid adaptive control for robot manipulators

Abstract

An adaptive control scheme is proposed for rigid-link robots where the control signal computations are performed continuously and the control coefficient computations are performed discretely. A global boundedness result is established for the resulting hybrid scheme, independent of the sampling rate. It is also shown that the position, velocity and acceleration tracking errors are of the order of the sampling period. This study brings the analysis of adaptive robot control closer to practice, where a discrete control law implementation is invariably used.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
