Automatic Control and System Dynamics
Lab


Overview

Research at the Laboratory of Prof. Dr.-Ing. habil. Stefan Streif is concerned with control, diagnosis, analysis and identification, verification, and classification of complex systems. Methods of control theory, modeling, applied mathematics, optimization, and computer science are synergistically combined, applied and further developed. Application areas are diverse and include automation, mechatronics, agricultural sciences, energy systems and systems biology. In addition to a solid method-oriented and theoretically well-founded research, the application relevance is attributed great importance. Thus, the research has a strong interdisciplinary focus. For this reason, the Lab cooperates closely with industrial and academic partners.

Mr. Sina Nahvi defended his research project on the topic Maschinelles Lernen für prädiktive Instandhaltung. The project was done in cooperation with Volkswagen Sachsen GmbH.

In a highly competitive process over the last two years, a project called CUBES Circles was selected for possible funding by the BMBF within the call "Agricultural systems of the future". In the project, several partners from academia and industry from Germany will be working together. The project is supposed to start in 2019 and will be coordinated by the Humboldt University Berlin. The ultimate goal of the project is to couple the resource and energy flows between different food production units to achieve resource and energy efficiency of the overall system. The Automatic Control and System Dynamics Lab at the TU Chemnitz will have a central role and will be responsible for the optimal control and scheduling of the flows between the coupled agricultural production systems.

Prof. Dr. Karl Worthmann is visiting our professorship on June 18-19, 2018. He conducts scientific discussions with the professorship staff and gives a lecture on suboptimality bounds of model-predictive control without stabilizing constraints. Prof. Worthmann is an expert in optimal control and nonlinear systems. He is also a project partner in KONSENS.

The ACSD Lab will present two papers on the European Control Conference, which takes place in Cyprus on June 12th-15th. New research results in the area of optimal and predictive control will be presented by Mr. Petzke and Mr. Beckenbach.

We are happy to have Prof. Didier Henrion from the LAAS-CNRS, University of Toulouse and the Czech Technical University in Prague as a guest in our lab. He will give a talk on Lasserre's hierarchy in polynomial optimization and special application to differential equations.
