Recently, SEE Li Quanfeng, as the first author with SDJU as the first author affiliation, in cooperation with team from the Department of Electrical Engineering, University of York, published Vibration Characteristics of Permanent Magnet Motor Stator System Based on Vibro-inertance Matrix Method and Sideband Vibration Suppression of Interior Permanent Magnet Synchronous Motors for Electric Vehicles under Multiple Operating Conditions on the IEEE TRANSACTIONS ON ENERGY CONVERSION and IEEE TRANSACTIONS ON TRANSPORTATION ELECTRIFICATIONS, two top journals in electronic and electric with universal recognition.
As electric vehicles (EV) have boomed these years, EV manufacturers have increasingly committed to making interior permanent magnet synchronous motor faster and smaller to lower cost and increase efficiency. Therefore, noise vibration and harshness (NEV) issues have become acute, especially when vehicles burn up the road, high-frequent sideband vibration will be generated by their controllers, causing serious high-frequent vibration noise. It is a hotspot in recent research on EV motor drive system. Issue-targeted, Li proposed a source-path-contribution (SPC) strategy for NEV reduction. To reduce sideband vibration and noise, an optimized scheme combining active disturbance rejection control (ADRC) and random frequency space vector pulse width modulation (RFSVPWM) was proposed to reduce high-frequency electromagnetic force and the vibro-inertance matrix of the stator system to further mitigate vibration.
The program lasted for three years in which Li studied in the Motor Control Lab at the University of York for one year. With close cooperation and resolved efforts facing difficulties, a string of breakthroughs was acquired. Therefore, their academic innovativeness earned editors’ recognition.
SEE’s efforts to globally publish high-standard academic papers manifest the new breakthrough in the research on EV motor drive systems and enhanced SDJU’s global academic influence with a particular focus on electric machines. (School of Electrical Engineering)
