In this article, multiple advanced low-switching-frequency modulation and control schemes are investigated for dual three-phase permanent-magnet synchronous motor (PMSM) drives. The modulation schemes under investigation include multisampling space vector modulation (MS-SVM), selective harmonic elimination pulsewidth modulation (SHEPWM), and synchronous optimal pulsewidth modulation (SOPWM), whereas the control schemes include complex vector control, model predictive control (MPC), and flux trajectory control-based model predictive pulse pattern control (MP3C). The difference between three-phase and dual three-phase PMSM drives at low switching frequencies is analyzed. Moreover, an optimal pulsewidth modulation (PWM)-based MP3C scheme is proposed for the dual three-phase PMSM, where the optimal PWM modulation and MP3C control are combined such that the optimal steady-state and dynamic control performance is achieved among the modulation and control schemes investigated. Experimental results are given to compare and validate the proposed control scheme.
