Modulated Model Predictive Current Control for PMSM Operating With Three-level NPC Inverter

Wang, Qi; Rivera, Marco; Riveros, Jose A.; Wheeler, Patrick

Abstract

In finite control set model predictive control (FCS-MPC) strategy only one basic voltage vector is to be selected in per periodic time, which causes big current ripple as well as the torque ripple of permanent magnet synchronous motor (PMSM). To solve this problem, an improved model predictive control method, named modulated model predictive control (M2PC) is proposed. The proposed control strategy can produce a modulated waveform, which can reduce torque ripple and improve power quality. Simulation results verify that the proposed current controller has a better control performance than the classical FCS-MPC strategy. Keywords-Finite control set model predictive control (FCS-MPC), inverter, neutral-point-clamped (NPC) inverter, predictive control, Modulated Model Predictive Control (M2PC).
