Title: Streamlining Data-Centric ML-Ops in the Integrated Control System at ESS
Supervisor: Johan Eker
Examiner: Bo Bernhardsson
Abstract: This thesis in collaboration with ESS proposes a workflow for developing, deploying, and integrating machine learning models into the control system. Machine learning offers a promising potential for control systems but often introduces technical debt, with the actual model code representing only a small fraction of the total code base. To address this a data-centric process is proposed for retrieving and selecting control time-series data, training ML models, and integrating them into the control system as process variables. The proposed workflow is tested and validated on the Cryogenic Moderator System. While the system primarily relies on PID controllers, their performance sometimes suffers from oscillations. Hence, the PID controllers need to be tuned. In this part we use ML to model the system, which enables the possibility to tune the PIDs.
