Fault-Tolerant Control for Nonsinusoidal Multiphase Drives With Minimum Torque Ripple

For nonsinusoidal electromotive force (NS-EMF) multiphase machines, this article proposes a new strategy and control scheme to guarantee smooth torque under an open-phase fault. Notably, the conventional proportional–integral controllers implemented for vector control in healthy mode can be used in the faulty mode. The strategy is based on reduced-order transformations while the control scheme app...
