NDLI: Simplified MPCC for four-switch three-phase inverter-fed PMSM

Content Provider	IET Digital Library
Author	Su, Junpan Sun, Dan
Abstract	A simplified model predictive current control (MPCC) for four-switch three-phase inverter (FSTPI)-fed permanent magnet synchronous motor (PMSM) considering the periodic fluctuation of the capacitor voltages is proposed. After analysing the inherent features of the FSTPI-fed PMSM system, an offset voltage vector and an ideal reference voltage vector are defined, which allows to deal with the reference voltage in the ideal voltage vector plane. Thus, the sector division is simplified. Furthermore, a concept of virtual duty cycle is introduced to employ an equivalent null vector in the MPCC in order to reduce the current ripples. Combining with a simple sector division, the active voltage vector and its virtual duty cycle are determined with only one prediction. Comparative experimental studies between the conventional and the proposed MPCC are executed to validate the feasibility of the proposed simplified MPCC.
