Abstract

This paper considers control of rigid robot manipulators with revolute joints in the absence of knowledge of the robot model physical parameters using only joint angular position feedback. A sliding mode observer is constructed to estimate the joint angular velocities. An adaptive estimation and control law is derived such that in the closed-loop system, the tracking error and the state estimation error asymptotically converge to zero. The adaptive controller includes a dynamic system in the feedback path and requires no knowledge of the robot's dynamics in its derivation.
