Compensation for Inverter Nonlinearity in Permanent Magnet Synchronous Motor Drive and Effect on Torsional Vibration of Electric Vehicle Driveline
Permanent magnet synchronous motors (PMSMs) with inverters are widely used in electric vehicles (EVs).However, current harmonics caused by the nonlinearity crimson tint dunks of the inverter generate torque ripples and give rise to torsional vibration in the vehicle driveline.This paper proposes a new compensation method to suppress the torque ripp
