Collision Avoidance Safety Filter for an Autonomous E-Scooter using Ultrasonic Sensors

no code implementations22 Mar 2024 Robin Strässer, Marc Seidel, Felix Brändle, David Meister, Raffaele Soloperto, David Hambach Ferrer, Frank Allgöwer

In this paper, we propose a collision avoidance safety filter for autonomous electric scooters to enable safe operation of such vehicles in pedestrian areas.

SafEDMD: A certified learning architecture tailored to data-driven control of nonlinear dynamical systems

no code implementations5 Feb 2024 Robin Strässer, Manuel Schaller, Karl Worthmann, Julian Berberich, Frank Allgöwer

The Koopman operator serves as the theoretical backbone for machine learning of dynamical control systems, where the operator is heuristically approximated by extended dynamic mode decomposition (EDMD).

Koopman-based feedback design with stability guarantees

no code implementations3 Dec 2023 Robin Strässer, Manuel Schaller, Karl Worthmann, Julian Berberich, Frank Allgöwer

We present a method to design a state-feedback controller ensuring exponential stability for nonlinear systems using only measurement data.

Decrypting Nonlinearity: Koopman Interpretation and Analysis of Cryptosystems

no code implementations21 Nov 2023 Robin Strässer, Sebastian Schlor, Frank Allgöwer

Our results on the required lifting dimension are in line with the intractability of brute-force attacks.

Robust data-driven control for nonlinear systems using the Koopman operator

no code implementations7 Apr 2023 Robin Strässer, Julian Berberich, Frank Allgöwer

Data-driven analysis and control of dynamical systems have gained a lot of interest in recent years.

Koopman interpretation and analysis of a public-key cryptosystem: Diffie-Hellman key exchange

no code implementations21 Nov 2022 Sebastian Schlor, Robin Strässer, Frank Allgöwer

In this paper, we introduce a new perspective on cryptosystems by interpreting the Diffie-Hellman key exchange as a nonlinear dynamical system.

Data-Driven Control of Nonlinear Systems: Beyond Polynomial Dynamics

no code implementations23 Nov 2020 Robin Strässer, Julian Berberich, Frank Allgöwer

While most existing approaches focus on systems with polynomial dynamics, our approach allows to design controllers for unknown systems with rational or general non-polynomial dynamics.
