This article proposes a modulated MPCC control strategy with virtual vectors and space vector modulation for regulating an asymmetrical six-phase induction machine. The strategy aims to improve stator current tracking, reduce harmonic content, and minimize x-y currents compared to other MPCC versions.
The use of multiphase machines has become a suitable choice in high-performance industry applications through advantages such as lesser torque ripple, enhanced current distribution per phase, and fault-tolerance capability. Among different control approaches for the regulation of multiphase drives, model-based predictive current control (MPCC) is one of the most analyzed strategies due to its adaptability and good dynamic response. However, this approach presents some disadvantages, e.g., high x - y currents and increased harmonic content in the fundamental alpha - beta stator currents. Modulation strategies have been combined with MPCC to overcome these shortcomings. This article proposes a modulated MPCC with virtual vectors and space vector modulation for the regulation of an asymmetrical six-phase induction machine to minimize the x - y currents, reduce the harmonic content, and perform improved stator currents tracking compared with other MPCC versions. Experimental tests are provided to demonstrate the quality of the proposed current control strategy.
