Research and Teaching Interest

Our research is focused on the motor drive control, electromagnetic compatibility, and dynamic control for Electric Vehicle. Transient dynamics and stability control methods are developed for two motors drive high speed tracked vehicle. Four In-Wheel-Motor Driven Vehicle Electronic Stability Control methods has been studied. Electromagnetic compatibility technology have been developed for electric vehicle motor system. Moreover, Model-based and measurement-based  method for electromagnetic interference from electric vehicle motor inverter system is proposed for EMC design at the early stage of product design to improve the electromagnetic compatibility of electric vehicles.
