ADAPTIVE SLIDING MODE CONTROL OF A 6-DOF RLED ROBOT MANIPULATOR WITH UNCERTAIN PARAMETERS AND EXTERNAL DISTURBANCES

Adaptive Sliding Mode Control of a 6-DOF RLED Robot Manipulator with Uncertain Parameters and External Disturbances

This paper addresses the end-effector position and orientation tracking problem of a 6-degrees of freedom (DOF) rigid link electrically driven (RLED) revolute joint serial robot manipulator with uncertain parameters and external disturbances.System uncertainties and external disturbances are bounded but their upper limits are unknown.The input matr
