Master Thesis on Data-Based Modelling of Electric Drives for Reinforcement Learning-Based Controller Design

Your tasks

The performance and efficiency of electric drives are fundamentally determined by their control methods and modulation schemes. While conventional approaches rely on simplified models and control structures, these limitations often restrict optimal performance in real‑world applications. Reinforcement Learning (RL) has emerged as a promising solution, offering the potential to enhance performance through more sophisticated models and control structures, e.g., direct switching control which directly manipulates the switching time instants of the inverter terminals. However, RL agents trained in simulation environments using simplified models frequently experience performance gaps when deployed in real‑world scenarios. The main objective of this thesis is the development of an innovative electric drive model suitable for a direct switching controller design using reinforcement learning.

• During your thesis you will conduct a comprehensive review of existing literature on data-based modeling techniques and advanced control strategies applied to electric drives.
• You will develop a novel and effective concept for systematically exciting electric drive systems. The primary objective is to generate rich and informative training data that accurately captures the switching behavior.
• Based on the collected training data and insights from the literature review, you will develop an advanced electric drive model that precisely captures the switching behavior combining physics‑based and data‑based modeling techniques.
• An optional extension involves training and evaluating a direct switching controller using reinforcement learning techniques and the developed models.
• Finally, you will thoroughly document all developed concepts and results culminating in a comprehensive thesis report.
