Abstract: Abstract This study proposes an improved predictive direct torque control (PDTC) of a five-phase permanent magnet synchronous motor fed by a five-leg inverter operating at a constant switching frequency. This approach is an effective solution to reduce the torque and stator flux high ripple, which is one the main drawbacks of conventional direct torque control. The core idea of this version of predictive torque control relies on calculating optimal vector application times to generate inverter switching states by selecting three voltage vectors; one of them is a zero voltage. In order to show the effectiveness and performance of the proposed control, a comparison with classical predictive direct torque control (PDTC) as well as with predictive direct torque control associated with space vector modulation (PDTC-SVM) is included. The simulation results clearly exhibit good performance and efficiency of the proposed approach compared to the aforementioned ones in term of ripples reduction.
