Abstract

The solution to numerous problems in control, diagnostics, signal processing and communication relies on a proper estimation of time derivatives with respect to signals that are known from online sampled data only, customarily, subject to severe noise levels. In this respect, the novel approach called algebraic derivative estimation, initiated by Fliess, Sira Ramirez and coworkers, is considered a promising method that may render possible a rapid and robust derivative estimation that does not need to be based on a system model. The intention of the talk is to give an exposition of the theoretical basics and to point out some applications of the method, among them: the state and parameter estimation in chaos-based communication schemes and the position estimation in underwater vehicles.

Biographical Information

Johann Reger obtained his diploma degree (Dipl.-Ing.) in mechanical engineering in 1999 and his doctorate (Dr.-Ing) in electrical engineering in 2004, both from the University of Erlangen-Nuremberg. Subsequent, he was postdoc research fellow with the mechatronics section at CINVESTAV-IPN in Mexico-City. Currently he is director in charge of the control laboratory affiliated to the institute of automation and control at the University of the German Armed Forces in Munich. He teaches automation engineering, nonlinear control, and gives laboratory courses in control. Centers of research: flatness- and passivity-based control of electrical drives and power converters, state and parameter estimation, fault diagnosis, and fault-tolerant control.
