From high gain adaptive control to funnel control

#IEEECSSDay #Systems #Control
Share
Funnel control is a powerful and simple nonlinear control method to solve the tracking problem for uncertain systems with prescribed transient performance as well as with guaranteed accuracy. The origin of the funnel controller can be seen in (adaptive) high gain feedback and the funnel controller resolves the major problems of high-gain feedback; in particular, arbitrary reference signals can be tracked arbitrary well and the feedback gain is not monotonically increasing. A simple proof is provided why funnel controller works and further theoretical extensions are discussed and illustrated with experimental setups and simulations.

Biography: 

Stephan Trenn received his Ph.D. (Dr. rer. nat.) within the field of differential algebraic systems and distribution theory at the
 Ilmenau University of Technology, Germany, in 2009. Afterwards, he held Postdoc positions at the University of Illinois at 
Urbana-Champaign, USA (2009-2010) and at the University of Würzburg, Germany (2010-2011). After being an Assistant Professor 
(Juniorprofessor) at the University of Kaiserslautern, Germany, he became Associate Professor for Systems and Control at the 
University of Groningen, Netherlands, in 2017. He is Associate Editor for the journals Systems & Control Letters, Nonlinear 
Analysis: Hybrid Systems, IEEE Control Systems Letters and DAE Panel. His research interests are switched systems, 
differential-algebraic equations and funnel control.
