Subject

At the moment, I work as part of the Collaborative Research Centre 1244, which is founded by the German Research Foundation (DFG). The CRC1244 "Adaptive Hulls and Structures for the Built Environment of the Future" aims at manipulating the structural response to any kind of loads by including actuators within a structure. This enables a better distribution of the loads within a structure, allowing for smaller and lighter elements. Additionally, the building can be equipped with virtual damping. All in all, this approach will help realize a great savings potential concerning the mass of conventional buildings, which is refered to as "gray energy". For high-rise buildings, this is mainly steel and concrete, each of which requiring high energy consumption for production.

The ISYS is involved in 6 scientific subprojects within the CRC (A05, A06, B02, B03, B04, Z01). Since 01/2021 the CRC is in its 2nd funding period. Besides my work as head of the civil systems engineering group, I am principal investigator of subproject B04 for this 2nd funding period. This project focuses on control concepts for adaptive structures with the following research items:

  • Modeling of large structures composed of different elements such as beam, rods, plates, etc.
  • Methods for finding a good substructure decomposition of complex structures based on dynamic and static coupling measures
  • Design of optimal decentralized controllers
  • wear-oriented control ("wear leveling")
  • Optimal input constraint distribution between static compensation and dynamic structural damping 
  • experimental validation on the demonstrator building (D1244)

The second part of B04 is concerned with modeling and control of new facade concepts, in detail:

  • Modeling a hydroactive facade (C01)
  • Modeling an adsorption facade based on zeolith (C06)
  • Design an optimal control algorithm to ensure following the long-term strategy (from A05) while considering short-term effects such as weather and changing user requirements
  • Modeling the indoor climate and user comfort
  • distributed parameter models of hygric and thermal states in front of the facade; interaction between indoor environment, facade and outside air

During the first funding phase (01/2017 - 12/2020) I have been working on subproject A06 and the following research questions:

  • How can adaptive elements be designed to integrate smoothly into conventional structures?
  • How can conventional passive structures be enhanced to become adaptive structure with the ability to actively manipulate them?
  • What are useful measures for choosing actuator and sensor positions?
  • How can thos measures be exploited for placing actuators and sensors?
 

During my PhD-studies from 08/2011 to 10/2017, my research focused on vibration analysis and compensation for the optical path of the Large Binocular Telescope (LBT). This project is a close cooperation with the Max-Planck-Institute for Astronomy in Heidelberg, Germany. Major parts of this work included:

  • Dynamic modelling of the telescope focussing on relevant vibrations
  • Identification and validation of the dynamic model
  • Deriving a state estimator for the telescope vibrations and thus the optical pathway difference
  • Controller synthesis for the opto-mechanical correction device

Additionally, I have worked on control of deformable mirrors used for adaptive optics systems. Thereby, my research was focused on:

  • Modeling the dynamics of the mirror membran
  • Optimization of sensor and actuator positioning
  • Design of observer based feedback algorithms for controlling the deformation of the mirror membrane
  • Responsible for the lab experiment "adaptive optics"
