Permanent magnet synchronous motors (PMSMs) with inverters are widely used in electric vehicles (EVs).However, current harmonics caused by the nonlinearity of the inverter generate torque ripples and give rise to torsional vibration in the vehicle driveline.This paper proposes a fr9352 new compensation method to suppress the torque ripples.This met
