“…In recent years, model predictive control (MPC) strategies have been investigated for the control of different variable speed drives equipped with induction, permanent magnets, and switched reluctance machines [4][5][6]. They have been widely implemented in sustainable mobility applications, covering electric [7][8][9][10] and hybrid [11][12][13][14] road vehicles, as well as aerospace ones [15,16]. MPC strategies have also been selected for the control of sustainable energy systems, especially wind turbines [17][18][19].…”

The paper deals presents a comparative study of the steady-state and transient behaviors of three-level neutral-point clamped (3L-NPC) inverter-fed induction motor (IM) drives under the control of three predictive torque control (PTC) schemes: the conventional one (C-PTC) and two new strategies involving selected stator voltage vectors (SVs), namely: (SV-PTC1) and (SV-PTC2). Compared to the C-PTC, the latter enable a reduction of the number of voltage vectors as well as the weighting factors. The introduced PTCs mainly differ by the cost function, which is more simple in the case of SV-PTC2. However, SV-PTC1 allows a systematic clamping of each stator phase to the DC bus voltage, at a low level of 60 degrees, and a high level at 60 degrees per cycle, while such a clamping is arbitrary in the case of SV-PTC2. Simulations prove the higher performances of the introduced SV-PTCs over the C-PTC ones, in terms of the reduction of the current distortion and of the torque ripple. Simulation results were validated by the experiments.
