Robotic Force Control using Observer-based Strict Positive Real Impedance Control

Johansson, Rolf LU and Robertsson, Anders LU (2003) In Proceedings. ICRA '03. 3. p.3686-3691
Abstract
This paper presents theoretical and experimentalresults on observer-based impedance control for forcecontrol without velocity feedback. As the velocity may notavailable to measurement, which is often the case for industrialrobots, an observer was designed to reconstruct velocityin such a way that it be useful for stabilizing feedbackcontrol and to modification of the damping in the impedancerelationship. A good model of the robot joint used wasobtained by system identification. Experiments were carriedout on an ABB industrial robot 2000 to demonstrate resultson observer-based SPR feedback applied in the design.Stability was shown via a modified Popov criterion.
