Shangjian Dai received the B.Eng. and M.Sc. degrees in electrical engineering from the Nanjing University of Aeronautics and Astronautics, Nanjing, China, in 2013 and 2016, respectively, and the Ph.D. degree in electronic and electrical engineering from The University of Sheffield, Sheffield, U.K., in 2021. He is currently a Professor at the School of Electrical Engineering, Southeast University. His research interests include high-speed and high-power motor drives and control.

High-speed permanent magnet synchronous machine drives (PMSM) have been increasing employed in electrified transportation applications, such as electric vehicle traction motors and generators in more electric aircraft, due to their high efficiency and high power-density. However, as speed increases, the resulting low switching-to-fundamental frequency ratio (SFR) presents significant control and drive challenges. Conventional field-oriented control (FOC), even with appropriate delay compensation, shows diminished dynamic response and stability at higher speeds. This talk will introduce a novel robust deadbeat predictive current control for high-speed PMSM drives, utilizing stator flux tracking and parameter robustness enhancement techniques. Experimental results demonstrate the advantages and potential of the proposed method for high-speed applications.
