In this paper, Direct Torque Control (DTC) algorithms for dual three-phase induction motor fed by six phases Voltage Source Inverter (VSI) is described. The induction machine has two sets of three-phase stator windings spatially shifted by arbitrary angle. The machine dynamic model is based on the vector space decomposition theory. Optimal switching strategies to control the machine for different...
This paper focuses on direct torque control (DTC) for three-phase AC electric drives. A novel model predictive control scheme is proposed that keeps the motor torque, the stator flux, and (if present) the inverter's neutral point potential within given hysteresis bounds while minimizing the switching frequency of the inverter. Based on an internal model of the drive, the controller predicts several...
