Abstract

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. Soft switching control is deployed, which reduces switching losses. At any instant, only one phase current is controlled, significantly reducing the control complexity. Simulations are carried out on a four-phase 8/6, 4kW SRM in MATLAB/Simulink.
