The Evolution of Model Predictive Control in Multiphase Electric Drives: A Growing Field of Research

Abstract

Multiphase electric machines (i.e., those with more than three phases) have completely remained in the shadow of their three-phase counterparts for a long time. The choice to build three-phase power systems made multiphase machines unable to make a direct connection to the network, and the development of high-performance multiphase electric drives was still not feasible in those early days. It was not until 1969 when the first proposal of a multiphase drive was recorded <xref ref-type="bibr" rid="ref1" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[1]</xref> , but little attention was paid to this field in the subsequent three decades. Although some basic foundations of multiphase electric drives were established in the 1990s <xref ref-type="bibr" rid="ref2" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[2]</xref> , the number of studies during the 20th century was very scarce <xref ref-type="bibr" rid="ref3" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[3]</xref> .
