Dr Clay (Guoyu) Chu is a Lecturer and Senior Research Associate in Energy Systems with the School of Electrical Engineering and Telecommunications, Âé¶¹Éçmadou Sydney. He is passionate about contributing to decarbonization through innovating more advanced electric drive and energy conversion technologies. He has recently been awarded the Australian Research Council's Early Career Industry Fellowship ($447k) and the Malcolm Chaikin Prize for Research Excellence in Engineering in 2023 for his research works in the more sustainable high-speed motor design and drive fields. The other awards and grants Dr Chu received includes the Australia’s Economic Accelerator Seed Grant ($198k), Âé¶¹Éçmadou DGFI Seed Fund ($25k), and Âé¶¹Éçmadou Faculty Infrastructure Funding ($350k).

Dr Clay Chu received his B.E. degree in electrical engineering and automation from the Shandong University of Science and Technology, China, in 2014, and the M.E. degree in electrical engineering from the Âé¶¹Éçmadou Sydney, Australia, in 2016. After completing his hardware engineer internship at Ventia, he joined Âé¶¹Éçmadou again in 2017 to pursue his Ph.D. degree in electrical engineering and received it with the Dean's Award in 2021.

His research interests include:

  • Design and optimization of high-speed electric machines
  • Permanent magnet synchronous motors & generators
  • Multiphysics multi-objective design optimizations
  • Sensorless drive and control of electric machines
  • Design and modelling of electromagnetic systems
  • Flywheel energy storage system (design, drive, and control)
  • Synchronous condenser and inverter-based systems for grid stability
  • Inertia and frequency control of grids with high renewable penetration
