Wuhan University team proposes structure-variable sliding mode control of IPMSM in EVs

Green Car Congress

Researchers at Wuhan University of Science and Technology in China have proposed a control method based on a speed loop structure-variable sliding mode controller (SMC) for interior permanent magnet synchronous motors in electric vehicles. Additionally, a wide speed range covers the constant torque, and the constant power region is desired.
