Enabling space-based solar power: dynamics and control of large space structures PhD

This fully-funded PhD research opportunity, supported by EPSRC Doctoral Landscape Awards (DLA) and Cranfield offers a competitive bursary of £22,000 per annum, covering full tuition fees. This PhD project will develop novel methods for modelling and controlling large space structures (LSSs), so that they can be reliably utilised in space-based solar power (SBSP) applications. Working with leading industrial SBSP experts, the candidate will explore the nonlinear structural dynamics of LSSs to fully understand the complexity of their control. They will use this foundation to explore idealised and realistic control laws to virtually 'stiffen' highly flexible components and ensure their energy harvesting capabilities. The project will deliver novel methods for modelling and controlling LSS structural dynamics in the extreme orbital environment. Objectives include undertaking an in-depth review of the literature on SBSP structures, LSS dynamics, and satellite control, developing analytical and finite element models to investigate nonlinear behaviour in LSSs, and developing novel control strategies to stabilise LSS shape, orbit & attitude. This project will be the first time the structural dynamics of LSSs of this type have been considered at this scale, representing an important contribution to the state of the art for large space structures. Successful candidates will develop important technical skills in spacecraft structural dynamics, controller design, and space systems. They will also develop soft skills such as project/time management, research development, and scientific communication. There is a generous travel budget for attendance at one or more international conference per year, including for personal development and training courses.
