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 in healthy mode can be used faulty mode. The is based on reduced-order transformations while applies simple artificial intelligence algorithm using specific online-trained adaptive linear neuron (ADALINE). Indeed, inputs of ADALINE require knowledge rotor position NS-EMF harmonic rank optimize learning time. proposed are tested seven-phase machine with strong total distortion (THD) NS-EMFs, containing numerous harmonics H k (THD = 38% 100% H1, 32.3% H3, 9.4% H7, 12.5% H9, 10.3% H11).
