Abstract
A controller for a switched reluctance machine (SRM) generates current commands that reduce torque harmonics generated by the SRM. The controller monitors the phase currents and rotor position of the SRM to estimate torque generated by the SRM. The current command signal is modified based on the difference between the torque command and the estimated torque. A multiplier that varies with the monitored torque command is applied to the modified current command to provide a smooth phase-to-phase transition.
