Model Predict Torque Control of Induction Motor Based on the DTC Switching Table

Compared to direct torque control (DTC), model predict torque control (MPTC) is more effective and accurate in VV (VV) selection. This paper presents a novel two-vector MPTC approach based switching table for induction motor drives. The proposed method contributes to significantly reduce torque ripples and stator current harmonics in conventional MPTC by using two VVs in one sampling cycle. The active VVs is determined based on switching table of DTC and cost function. The validity of the proposed method is verified through simulations.
