A model predictive current controller for multi-level inverter driving electrical machines is proposed that keeps the stator currents within given bounds around their respective references and balances the inverter's neutral point potential around zero. The inverter switch positions are directly set by the controller thus avoiding the use of a modulator. Admissible switching sequences are enumerated...
Model Predictive Direct Torque Control (MPDTC) is a recent computational control methodology that combines the merits of Model Predictive Control (MPC) with the ones of Direct Torque Control (DTC). Specifically, with respect to standard DTC, the converter's switching frequency and/or losses are considerably reduced, while at the same time the Total Harmonic Distortion (THD) levels of the phase currents...
