Time-varying optimal control under measurement errors
Patrick Schmidt, Stefan Streif
Solving optimal control problems to determine a stabilizing controller involves a significant computational effort. Time-varying optimal control provides a remedy by designing a tr…
A Tutorial to Multirate Extended Kalman Filter Design for Monitoring of Agricultural Anaerobic Digestion Plants
Simon Hellmann, Terrance Wilms, Stefan Streif +1
In many applications of biotechnology, measurements are available at different sampling rates, e.g., due to online sensors and offline lab analysis. Offline measurements typically…
Strong nonlinear detectability and moving horizon estimation for nonlinear systems with unknown inputs
Yang Guo, Jaime A. Moreno, Stefan Streif
This paper considers state estimation for general nonlinear discrete-time systems subject to measurement noise and possibly unbounded unknown inputs. To approach this problem, we f…
MHE in Output Feedback Control of Uncertain Nonlinear Systems via IQCs
Yang Guo, Stefan Streif
We propose a moving horizon estimation (MHE) scheme for general nonlinear constrained systems with parametric or static nonlinear uncertainties and a predetermined state feedback c…
Modularized data-driven approximation of the Koopman operator and generator
Yang Guo, Manuel Schaller, Karl Worthmann +1
Extended Dynamic Mode Decomposition (EDMD) is a widely-used data-driven approach to learn an approximation of the Koopman operator. Consequently, it provides a powerful tool for da…
