Predictive Torque Control for five-phase induction motor drives

Multiphase electric drives have been recently proposed for applications where the highest overall system reliability, combined with a reduction in the total power per phase, are required. Strategies like Field Oriented Control (FOC) and Direct Torque Control (DTC) have been traditionally used in these high performance applications. In this paper, a Predictive Torque Control (PTC) method is introduced as an alternative to FOC and DTC methods. Simulation results are provided to illustrate the potential of the presented control technique, comparing the speed, torque and current performances with those obtained by applying FOC and DTC methods.
