„Stability Guarantees and Resource Savings in Cyber-Physical Systems“


Cyber-physical systems (CPS) are digital systems that monitor and control diverse physical processes, from chemical plants to smart factories. The use of low-cost, battery-powered devices and shared wireless networks facilitates the adoption of CPS where traditional architectures (e.g., based on wired busses) are infeasible. Severe resource constraints and the notorious unreliability of wireless communications, however, call for a novel design methodology to provide guarantees on closed-loop stability while using the available resources as efficiently as possible.

In this talk, we will present our work to address these needs through a careful co-design of the wireless network components and the closed-loop control system. We will detail how our approach enables implementations whose end-to-end control properties and resource savings can be rigorously analyzed but also validated on real experimental CPS featuring fast physical systems. We will conclude with perspectives on our joint research, combining expertise from control and wireless embedded systems, toward CPS that are provably dependable, highly adaptive, and resource-efficient by design.


Sebastian Trimpe is a Full Professor at RWTH Aachen University, where he heads the newly founded Institute for Data Science in Mechanical Engineering (DSME) since May 2020. Research at DSME focuses on fundamental questions at the intersection of control, machine learning, networks, and robotics. Before moving to RWTH, Sebastian was a Max Planck and Cyber Valley Research Group Leader at the Max Planck Institute for Intelligent Systems in Tübingen/Stuttgart, where he keeps a side appointment at present. Sebastian obtained his Ph.D. degree in 2013 from ETH Zurich with Raffaello D'Andrea at the Institute for Dynamic Systems and Control. Before, he received a B.Sc. degree in General Engineering Science in 2005, a M.Sc. degree (Dipl.-Ing.) in Electrical Engineering in 2007, and an MBA degree in Technology Management in 2007, all from Hamburg University of Technology. In 2007, he was a research scholar at the University of California at Berkeley. Sebastian is recipient of the triennial IFAC World Congress Interactive Paper Prize (2011), the Klaus Tschira Award for achievements in public understanding of science (2014), the Best Paper Award of the International Conference on Cyber-Physical Systems (2019), and the Future Prize by the Ewald Marquardt Stiftung for innovations in control engineering (2020).


Marco Zimmerling, full Professor at the University of Freiburg of the Networked Embedded Systems Lab Currently, he is an Independent Research Group Leader at TU Dresden. He holds a PhD in Computer Engineering (2015) from ETH Zurich, Switzerland, and a Diploma in Computer Science (2009) from TU Dresden. For his Diploma thesis project he spent seven months in Sweden, collaborating with RISE SICS and Uppsala University. In 2006 he did a six-month internship at the IBM T.J. Watson Research Center, Hawthorne. His research revolves around embedded systems and wireless networking, with the goal of designing dependable and sustainable networked systems that can power emerging cyber-physical systems and the Internet of Things. His work has been recognized through several awards, including the 2015 ACM SIGBED Paul Caspi Memorial Dissertation Award, the 2016 EDAA Outstanding Dissertation Award, and Best Paper Awards at ACM/IEEE ICCPS 2019, ACM SenSys 2013, and ACM/IEEE IPSN 2011.
