Our former group member Florian Joch receives the university award for the best thesis in 2021 of the Faculty of Electrical Engineering and Information Technology. His master thesis is entitled 'Konzeptionelle Analyse sowie Vergleich von Ansätzen zur Schlupfregelung in Zügen' (Conceptual analysis and comparison of approaches to slip control in trains). Siemens AG is the sponsor of the award.

An insight about the interplay of insect larvae (Hermetia illucens), fish farming and crop production was given the webpage of Wirtschaftsjahr. The described topic is a part of the CUBES project and a branch of our research, where methods for sustainable food production are investigated.

We published an article on “epidemic management with admissible and robust invariant sets” in collaboration with Jean Lévine (MINES ParisTech). The full article is available on the webpage of Plos One.

Our team member Michael Hauck receives the university award for the best thesis in 2020 of the Faculty of Electrical Engineering and Information Technology. His master thesis is entitled 'Control-Oriented Modeling of the Anode Recirculation and Purging Processes in PEM Fuel Cell Systems'. Siemens AG is the sponsor of the award.

During the 21st IFAC World Congress 2020 one of the many contributions of our lab was publishing PoCET, a Polynomial Chaos Expansion Toolbox for Matlab. It offers a powerful set of routines that allow for fast uncertainty propagation through linear and nonlinear ODE systems and can therefore be used for all kinds of stochastic dynamic optimization problems like parameter estimation, experimental design, or MPC. Moreover, it is available completely open-source and free of charge on GitHub. More information on PoCET can be found on the corresponding research page.

In a new project, the group will contribute its expertise in set-based methods, dynamical models of the infectious disease and optimal control to design and analyse mitigation actions. The project results will hopefully contribute to mitigate the spread of the Corona virus. Further information can be found in this press release from TU Chemnitz. An overview of our projects can be found here.

Our ACSD lab is part of the new research project SOPRANN (synthesis of optimal controls and adaptive neural networks for mobility applications). The project focuses on (proveable) safe learning-based control using neural networks in mobility applications. Further information can be found in this press release from TU Chemnitz. An overview of our projects can be found here.

The IFAC World Congress 2020 is one of the most important control conferences. The ACSD lab will publish and present 16 contributions covering a variety of topics, including theoretical contributions in the areas of learning-based control, model predictive control and set-based system analysis as well as application oriented contributions in the area of energy networks and agricultural systems:

  • Maintaining Hard Infection Caps in Epidemics via the Theory of Barriers
  • Sustainability Analysis of Interconnected Food Production Systems via Theory of Barriers
  • Model Predictive Control of a Food Production Unit: A Case Study for Lettuce Production
  • Nonsmooth stabilization and its computational aspects
  • Online Traction Parameter Identification and Mapping
  • Optimal control of centrifugal spreader
  • A reinforcement learning method with closed-loop stability guarantee
