PhD Fellowship in Methods for Linearising Switched and Quantised Systems

Job description

The University of Stavanger invites applications for a 3-year PhD Fellowship in Methods for Linearising Switchedand Quantised Systemsat the Faculty of Science and Technology, Department of Energy and Petroleum Engineering . The appointment is for three years with research duties exclusively.

This is a trainee position that will give promising researchers an opportunity for academic development through a PhD education leading to a doctoral degree.

The hired candidate will be admitted to the PhD program in Science and technology. The education includes relevant courses to about six months of study, a dissertation based on independent research, participation in national and international research environments, relevant academic communication, a trial lecture and public defence. Read more about the PhD education at UiS on our website.

Information about the project

The PhD Fellow will be affiliated with the following project "Ultra-linear Digital-to-analogue Conversion".

The project aims to develop methods for linearising switched and quantised systems. Existing methods include pulse-width modulation, delta-sigma modulation, noise-shaping, dithering and model-predictive control. The project will aim at developing methods suitable for high bandwidth and low computational complexity.

The ability to use control signals to smooth non-linearities has been known in control engineering since the 1940's, and was successfully applied to reduce friction (mechanical lubrication) in cannon turrets and quench limit cycles due to non-linear valves in hydroelectric power plants. In more recent years such methods has been extensively used in power electronics to improve power quality and reliability, to achieve "super-resolution" in digital signal processing: e.g. for image processing (most notable the Hubble space telescope), distortion-free re-quantisation between data types, or high-fidelity audio recording.

All participants in the project bring unique and important qualities with them into the doctoral programme. The PhD candidate will have the opportunity to collaborate with researchers in the partner institutions and benefit from these collaborative research and education activities. The group you will be joining has used dithering techniques to build the highest resolution digital-to-analogue converter known in the literature and will serve as the starting point of the current project. The project is a collaboration between the University of Stavanger, Norwegian University of Science and Technology, Aalborg University, Justervesenet (Norwegian Metrology Service) and Eindhoven University of Technology, as well as The University of Newcastle, Australia. An extended research stay at one or more of these institutions is encouraged.

The main objective for this position is to develop linearising methods applicable to switched and quantised systems, specifically

• developing new methods and comparing to existing methods,
• determining properties when introducing feedback (closed-loop applications),
• and investigating applications such as power electronics and drives

The work can focus on experimental results in the lab or be more oriented towards theory, depending on the candidate's background and interests.

As part of the project team, you will work alongside other highly motivated and talented PhD candidates and researchers. You will also have access to the knowledge base, state-of-the-art research infrastructure, and impact orientation of the partners in the team.
