An easily attainable and effective bilateral control for teleoperation

Teleoperating system has been developed for several decades, and many control schemes for it have been suggested. But the implementation for real applications needs a very effective but simple controller. In this paper, an advanced control scheme to achieve this objective is suggested, which is the combination of a modified internal model controller and a variable filter for force reflection. The effectiveness of the proposed scheme is verified through experiment. Both responses of unconstrained and contact motions for the testbed-walls with different stiffness are shown
