On the (non-)resilience of encrypted controllers to covert attacks
Philipp Binfet, Janis Adamek, Moritz Schulze Darup
The security of networked control systems (NCS) is receiving increasing attention from both cyber-security and system-theoretic perspectives. The former focuses on classical IT sec…
On the Effect of Quadratic Regularization in Direct Data-Driven LQR
Manuel Klädtke, Feiran Zhao, Florian Dörfler +1
This paper proposes an explainability concept for direct data-driven linear quadratic regulation (LQR) with quadratic regularization. Our perspective follows the parametric effect…
A moving horizon estimator for aquifer thermal energy storages
Johannes van Randenborgh, Moritz Schulze Darup
Aquifer thermal energy storages (ATES) represent groundwater saturated aquifers that store thermal energy in the form of heated or cooled groundwater. Combining two ATES, one can h…
MPC for Aquifer Thermal Energy Storage Systems Using ARX Models
Johannes van Randenborgh, Moritz Schulze Darup
An aquifer thermal energy storage (ATES) can mitigate CO2 emissions of heating, ventilation, and air conditioning (HVAC) systems for buildings. In application, an ATES keeps large…
A lightweight numerical model for predictive control of borehole thermal energy storages
Johannes van Randenborgh, Steffen Daniel, Moritz Schulze Darup
Borehole thermal energy storage (BTES) can reduce the operation of fossil fuel-based heating, ventilation, and air conditioning systems for buildings. With BTES, thermal energy is…
On data usage and predictive behavior of data-driven predictive control with 1-norm regularization
Manuel Klädtke, Moritz Schulze Darup
We investigate the data usage and predictive behavior of data-driven predictive control (DPC) with 1-norm regularization. Our analysis enables the offline removal of unused data an…
