This study presents finite set-predictive torque control (FS-PTC) with discrete space vector modulation (DSVM) for indirect matrix converter (IMC)-fed
permanent magnet synchronous motors (PMSMs). The implementation of FS-PTC with DSVM in an IMC requires high computation time due to the
large number of synthesized voltage vectors (VVs). To reduce computation time caused by considering all VVs, a new preselection strategy is
proposed to reduce the computational numerations from 37 to 6 VVs. The proposed algorithm can reduce torque and flux ripples and achieve
robust characteristics against parameter variations. Additionally, the increased degree of VVs can improve the correlation between the rectifier and
inverter sides of the IMC. The eectiveness of the proposed method is verified by simulation and experimental results.
