Interconnected Automation Systems (IAS)

At the Chair of Interconnected Automation Systems (IAS) at the University of Siegen, we drive basic and applied research on design automation of software and hardware to improve the reliability, efficiency and sustainability of modern cyber-physical infrastructures - from industrial and mechatronic systems to energy conversion applications and electrical power systems.

New IEEE Transaction on Power Electronics Publications on Meta-Reinforcement Learning

Together with our partners at the University of Paderborn, we recently published an article in IEEE Transactions on Power Electronics entitled “Universal Direct Torque Controller for Permanent Magnet Synchronous Motors via Meta-Reinforcement Learning.” The article addresses highly automated controller synthesis for any permanently excited synchronous drives and demonstrates how a control strategy learned using data-driven algorithms can be transferred from simulative training to real-world laboratory applications. The methodology and empirical investigation presented represent an important step toward the autonomous commissioning of power electronic systems in heterogeneous application contexts in order to achieve optimal system performance with minimal (human) effort.

Mission statement

Portrait Oliver Wallscheid

We conduct rigorous, open and responsible research on interconnected automation systems and translate sound modeling, control and data-driven methods into trustworthy technologies that increase safety and reliability, reduce energy plus resource consumption and strengthen resilient infrastructures for the benefit of society. In teaching, we qualify engineers and researchers to combine a physical-analytical understanding of systems with computer-aided and data-oriented tools so that they can actively shape future generations of automation and energy systems.

Research profile

We research networked cyber-physical systems in industrial automation and mechatronics as well as in electrified energy technologies. Central fields of application are electric drives, power electronic converters, energy storage systems and charging infrastructures as well as networked electrical energy systems such as microgrids - with the aim of enabling more reliable, efficient and resilient operation under real operating conditions.

 

Our work covers the entire innovation chain from basic research to industrial transfer. A particular focus is on translating theoretical concepts into practical proof-of-concepts, supported by rapid software and hardware prototyping. Experimental validation, including targeted measurement campaigns on relevant test benches, is an integral part of our research process.

 

Open science is a cornerstone of our research practice. We publish open source software, reproducible workflows and other open resources to enable transparent evaluation, benchmarking and rapid knowledge transfer for students, researchers and industry partners. Our open source contributions can be found on GitHub: https://github.com/IAS-Uni-Siegen

Focus areas

  • Optimal control methods (e.g., reinforcement learning, differential predictive control)
  • Hardware design, optimization and testing of power electronic converters (component and system level)
  • Hybrid modeling and system identification (combination of expert and data knowledge)
  • Condition monitoring, diagnostics and digital twins (e.g. using fault and anomaly detection)
  • State and parameter estimation (observer, co-estimator)
  • Software-driven automation (reproducible design toolchains, verification and benchmarking)
