Adaptive computed torque control for rigid link manipulators
Abstract
In this paper we shall examine the adaptive control of rigid link manipulator systems. We give a parameterization of a genereal rigid body which yields dynamic equations that are linear in the unknown parameters. Standard linear estimation techniques together with an adaptive computed torque control law are shown to give a globally convergent adaptive system which does not require measurements of accelerations or additional torques.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
