N2 - This article proposes an assessment of constrained parallel structure predictive torque control (PPTC) with parameter robustness improvement for induction machine (IM) drive fed by voltage source inverter (VSI). Due to the inherent weakness of weighting factor determination in conventional PTC scheme, the proposed PPTC employs the objective terms to be constrained in the boundaries, and then voltage vectors (VVs) are carried out in an adaptive selection mechanism. Therefore, the exploratory process of parameter tuning is not required. However, the parallel structure in its optimization stage is penalized by the parameter variation in the control plant. To solve this problem, a sliding-mode disturbance observer (SMDO) is used for the robustness enhancement of the proposed scheme to parameter mismatch. Experimental validations are conducted to confirm the effectiveness of the proposed disturbance observer and reduced parameter sensitivity of the robust PPTC methodology.
