Predictive current control based pseudo six-phase induction motor drive

Asymmetrical six-phase induction machines are widely used in high-power safety-critical applications. The so-called pseudo winding layout has recently been proposed as a promising contender for high power medium voltage applications terms of torque density, phase current quality, simple single-layer-based stator design, and fault-tolerant capability. This employs quadruple three-phase sets connected to provide only six terminals, while being fed from two inverters. Therefore, the same conventional six-phase-based control structure can still be employed. Among different techniques, model predictive is considered one cutting-edge technologies multiphase drive systems, thanks its simplicity flexibility defining new objectives. paper investigates how available 64 vectors inverter classified among subspaces when employing winding. Moreover, required modifications classical (PCC) introduced order properly machine manner similar asymmetrical ensuring minimum circulating xy components. concept virtual (VVVs) also employed further enhance quality. controller validated using 2Hp prototype under operating conditions. An experimental comparative study with an carried out verify claimed equivalence.
