Vibration Control of a Large Flexible Manipulator by a Small Robotic Arm

Abstract

The vibration of a large flexible manipulator is suppressed by inertial forces induced by the joint torques of a small arm which is located at the tip of the large manipulator. The control of the small arm is studied based on a slow and fast submodel which are derived by applying the singular perturbation technique. A composite controller is designed to control the slow and fast motion.
