Abstract :
In this paper, a predictive direct torque control (DTC) scheme for split phase induction machine (SPIM) is established. The induction motor has two sets of stator three-phase windings spatially shifted by 30 electrical degrees. The major drawback of SPIMs is occurrence of extra harmonic currents. Thus in the DTC of SPIMs in addition to control of torque and flux we should consider simultaneously minimizing harmonic components of stator current. Predictive DTC along with optimized SVPWM is used in this paper. Simulation results show that in addition to a good dynamic response, current harmonics in this scheme is significantly reduced.
