About the Project

Hysteresis describes the phenomenon in which the value of a physical property lags behind changes in the effect causing it. Hysteresis loops arise in many engineering fields and pose interesting challenges to the control of the underlying systems. For example, dynamic stall is a hysteresis effect that occurs when airfoils rapidly change the angle of attack, requiring special considerations in handling stall onset and recovery.

This project will focus on the modelling and control of hysteresis effects, under the framework of numerical optimal control. The aim is to develop advanced algorithms that would allow the delay and/or suppression of hysteresis effects in dynamic stall through the use of control surfaces, for example, allowing the safe recovery of aircraft from post-stall conditions without entering secondary stalls.

Upon the successful completion of this project, the PhD candidate will gain expertise in both hysteresis modelling and numerical optimal control. The candidate will also be well positioned to address the dynamic stall challenges arising from aerospace and wind energy applications.
