A Novel Matrix Transformation for Decoupled Control of Modular Multiphase PMSM Drives

When multiphase drives are used for specific applications, the modular solutions preferred as they use consolidated power electronics technologies. The literature reports two modeling approaches machines having a configuration of stator winding. first approach is vector space decomposition (VSD) that models energy conversion an equivalent three-phase machine. main alternative to VSD multistator (MS) emphasizes machine modularity in terms torque production. Both have advantages and disadvantages with structure. Therefore, this article aims combine MS approaches, defining new matrix transformation and, hence, developing proposed allows decoupled independent control sets composing machine, preserving regulation's modularity. Together scheme, it has been applied permanent magnet synchronous (PMSM) nonstandard spatial shift between windings. Experimental results presented nine-phase PMSM prototype triple-three-phase winding configuration.
