Minimization of Torque Ripple in Switched Reluctance Motor Drives Using an Enhanced Direct Instantaneous Torque Control

Torque ripple is an inherent characteristic of switched reluctance motor drives due to its double salient geometry and it is a serious drawback in applications that require smooth torque and high dynamic performances. This paper presents new contributions to the minimization of torque ripple in SRM using an enhanced direct instantaneous torque control. Torque ripple is reduced by adding a PI controller before the instantaneous torque controller and a change in the commutation zones. The PI direct instantaneous torque controller (PI+DITC) is simulated using Matlab/Simulink and then implemented in a DSPACE ACE kit 1006 CLP. Finally, experimental results are shown and they are compared with those obtained using conventional direct instantaneous torque control.
