Adaptive Neural Network Finite-Time Tracking Control for Uncertain Hydraulic Manipulators

Abstract

Motivated by the challenges associated with achieving rapid convergence and high accuracy in tracking errors for$\bm n$-DOF uncertain hydraulic manipulators, this article delves into an adaptive neural network (NN) finite-time control scheme. Initially, we propose an integrated finite-time dynamic surface control framework geared toward achieving swift convergence of tracking errors. Unlike conventional backstepping control schemes, this introduced dynamic surface control scheme adeptly circumvents computational complexity and singularity issues stemming from iterative derivatives of the virtual control input. Moreover, as accurate dynamic models of hydraulic manipulators are not readily available due to the substantial coupling between joints and the intricate nonlinearities, we introduce two adaptive NNs to encapsulate the complex coupled mechanical dynamics and uncertain hydraulic dynamics, respectively. The weight update laws for the adaptive NN are formulated utilizing convex optimization techniques and the gradient descent method, thereby accelerating the convergence of NNs compared to traditional weight update law construction methods. Finally, experimental studies conducted on a six-DOF hydraulic manipulator platform are presented to substantiate the efficacy of the proposed methodology.

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.
