Enhanced predictive torque control for open end winding induction motor drive without weighting factor assignment

REK Meesala, VPK Kunisetti… - IEEE Transactions on …, 2018 - ieeexplore.ieee.org
Nowadays, predictive torque control (PTC) is the most popular control technique in the field
of electric drives. This PTC strategy is introduced for open end winding induction motor
(OEWIM) drive in view of advantages. The conventional PTC offers a single-cost function
where torque and stator flux control objectives are present. Since these control objectives
are dissimilar, weighting factor designation to the respective control objective is essential.
Weighting factor tuning by an empirical approach leads to a cumbersome control process …

Predictive torque control of open‐end winding induction motor drive fed with multilevel inversion using two two‐level inverters

KV Praveen Kumar… - IET Electric Power …, 2018 - Wiley Online Library
This study proposes direct torque and flux control of dual‐inverter‐fed open‐end winding
induction motor (OEWIM) with the help of model predictive control. OEWIMs are extensively
used in electric vehicles and for ship propulsion but they require a high dynamic
performance. Predictive torque control (PTC) retains the features of direct torque control and
offers a high dynamic performance by eliminating start‐up problems. In this study, predictive
torque control is implemented for multilevel inversion‐fed OEWIMs. Multilevel inversion is …
