PhD Studentship - Uncertainty in Electromechanical Actuators

Loughborough University

Start date: 1st October 2018

Closing date: 9th March 2018

Supervisors:

Primary supervisor: Dr Will Midgley

Secondary supervisor: TBC

Intro (standard):

Loughborough University is a top-ten rated university in England for research intensity (REF2014) and an outstanding 66% of the work of Loughborough’s academic staff who were eligible to be submitted to the REF was judged as ‘world-leading’ or ‘internationally excellent’, compared to a national average figure of 43%.

In choosing Loughborough for your research, you’ll work alongside academics who are leaders in their field. You will benefit from comprehensive support and guidance from our Graduate School, including tailored careers advice, to help you succeed in your research and future career.

Project Detail:

Electric machines are increasingly being used to automate processes throughout manufacturing value chains. However due to mechanical tolerances, component wear and manufacturing variations, the way these machines react to actuation commands can be uncertain.

The traditional way to approach these uncertainties is to measure the system response and use a control algorithm to correct the actuator accordingly. This project aims to construct a novel framework for understanding the uncertainty in electromechanical systems, and to use this framework to identify methods for controlling the system more effectively.

This project will include a theoretical component focussed on the underlying theory of uncertainty and optimal control, and a practical component investigating the real-world behaviour of uncertain electromechanical actuators.

Entry requirements:

Applicants should have, or expect to achieve, at least a 2:1 Honours degree (or equivalent) in Mechatronics Engineering or a related subject. A relevant Master’s degree and/or experience in one or more of the following will be an advantage: MATLAB, Simulink, uncertainty, nonlinear interactions/dynamics, control theory and optimisation.

Funding information:

The studentship will start in October 2018, for three years, and provides a tax-free stipend of £14,786 per annum( provisional) plus tuition fees at the UK/EU rate (currently £4,195 p.a.). While we welcome applications from non EU nationals, please be advised that it will only be possible to fund the tuition fees at the international rate and no stipend will be available. Successful candidates will be notified by 30th April 2018.
