Modular Converter-Based Predictive Current Control of SRM for Torque Ripple Suppression

A torque sharing function with online compensation of excitation current control method for torque ripple reduction in electric excitation auxiliary switched reluctance motor drives

“…In addition, the higher the speed and the shorter the commutation time, the greater the torque ripple. Therefore, the TSF control is more suitable for low and medium speed SRMs [22, 23].…”

“…However, the harmonic current will increase the copper loss and the system efficiency will also be reduced. Some references also proposed to use TSF control to reduce the torque ripple [20,21]. This method does not need to adjust the function according to the number of stator and rotor poles, nor does it generate negative torque which reduces the efficiency of the system.…”
