Abstract
One of the most attractive features of multiphase machines is the fault-tolerant capability it possesses due to the higher number of phases. Different post-fault control strategies based on hysteresis, Pi-resonant and predictive techniques have been recently proposed. They all proved their capabilities to withstand fault situations and to preserve the fundamental component of the air-gap field, while achieving minimum losses, maximum torque per-ampere and reducing torque vibrations. Nonetheless due to its recent implementation, no thorough study has been done comparing the performance of these controllers. In this paper two open-phase fault-tolerant control schemes, based on Pi-resonant and predictive control techniques, for five-phase induction machines, are compared through simulation results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
