Adaptive control of two-link manipulator via dynamic neural network

Abstract

A neurocontrol method for robot manipulators is presented. A single-layer dynamic neural network is used to estimate the unknown manipulators, then a direct linearization controller is derived based on the neuro identifier. Because the approximation capability is limited, another PD-like controller is applied to compensate the unmodeled dynamics. The main contribution of the paper is that the boundness of the identification error and tracking error are established.
