A New Torque Ripple Minimization Approach for Switched Reluctance Drives
2022 IEEE 1st Industrial Electronics Society Annual On-Line Conference (ONCON), 2022 This paper presents a new torque control function for torque ripple reduction in switched reluctance drives. The approach is based on the maximum utilization of available dc link voltage, extending the zero torque-ripple speed range. The approach is suitable for switched reluctance machines with any number of phases and stator/rotor poles.
