Approaches for Control of System in Adaptive Optics

Abstract: In the talk control problems in adaptive optics will be presented. After a short introduction the functionality of these systems will be explained and ways to derive a dynamic model discussed. These approaches lead to partial differential equations, which can be analyzed by modal approaches. By the modal representation, a feed-forward control strategy by system inversion is developed and the effectiveness discussed by several measurement experiments. In the talk, several methods for feedback control of theses systems are discussed continued by several examples control problems in astronomical instruments.

Bio: Dr. Oliver Sawodny received his diploma degree in electrical engineering from University of Karlsruhe/Germany in 1991 and his PhD degree from University of Ulm/Germany in 1996. In 2002 he became full professor at Technische Universität Ilmenau and moved in 2005 as Director of the Institute for System Dynamics to Universität Stuttgart. His research interest includes methods of differential geometry, trajectory generation, methods and application to mechatronic systems.
