Title:Passivity Based Backstepping Control of an Elastic RobotAuthor(s):Peter Staufer,  Hubert Gattringer,  Wolfgang Höbarth,  Hartmut BremerAbstract:In industry plants, a trade of between the requirements of speed and cost efficiency often results in lightweight constructions. However, this introduces elastic deflections causing vibrations and a loss in tracking precision. Hence, investigations in suitable models and control laws are necessary. By using the Projection Equation with a Ritz expansion, a set of nonlinear ordinary differential equations which describes the motion of the system is developed. The utilized control law is a combination of a feedforward and a feedback scheme. The latter is based on backstepping methods, with respect to passivity ports. Finally experimental results are shown to verify the proposed control strategy.Booktitle:Romansy 18, Robot Design, Dynamics and ControlPublisher:Springer Wien New YorkEditor(s):Vincenzo Parenti-Castelli, Werner SchiehlenISBN:978-3-7091-0276-3Page Reference:page 315-322, 8 page(s)Publishing:2010Volume:524Number:524
