Switched reluctance motor: torque-sharing control

Reduce the torque ripple of a switched reluctance motor by sharing torque smoothly between phases.

Aim

Compare conventional current chopping control (CCC) with a torque-sharing function (TSF) on an SRM drive and measure the torque-ripple reduction.
