  • Abstract
    This paper demonstrates DOB-based PD+gravity compensation control for flexible joint robots (FJRs). By virtue of the DOB, the controller can recover global asymptotic stability under the friction. One important difference from the typical DOB implementation is that the nominal signal feedback is required, instead of the real (measured) signal feedback.
