Master Thesis – Reinforcement Learning Control of a Liquid–Liquid Separator Using Physics-Informed Neural Networks
At the Institute of Climate and Energy Systems - Energy Systems Engineering (ICE-1) we focus on the optimal design and operation of integrated, decentralized energy systems with a high share of renewable energy. Computer simulation and numerical optimization are our essential tools to arrive at efficient, reliable, and cost-effective solutions. We contribute both to the development of mathematical models and to the development of improved simulation methods and optimization algorithms. Our methods and software-tools are validated against operating data of real systems. Furthermore, we conduct comprehensive case studies in order to test and further improve the scalability and the performance of our models and algorithms. Specially adapted methods and codes enable us to exploit the potential of high-performance computing with the aim of solving particularly large and complex problems.
Your Job
- Develop a reinforcement learning (RL) controller for a liquid–liquid gravity settler, trained entirely offline in a simulated environment
- Use existing physics-informed neural network (PINN) models of the separator dynamics as fast virtual training environments
- Formulate the control problem and design reward functions for operating objectives such as throughput and separation quality
- Handle process constraints during learning
- Evaluate the trained controllers on a more detailed process model to assess how well the learned policies carry over beyond their training environment
Validated surrogate models and experimental data from a pilot-scale settler are available. The project offers close supervision from doctoral researchers in machine learning and process control.
Your Profile
- Current master's student in Process Systems Engineering, Computational Engineering Science, Chemical Engineering or a comparable program
- Programming experience in Python; experience with PyTorch is a plus
- Experience in modeling, simulation and machine learning
- Basic knowledge of control engineering
- Experience in reinforcement learning is not required but highly beneficial
- Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the CEFR), ideally supported by a certificate confirming the language level
- High degree of independence, motivation and reliability / independent and analytical working style
- Excellent ability to cooperate and work in a team
