ABSTRACT In this article, predictive torque control (PTC) of multi-level inversion (MLI) fed open-end winding induction motor (OEWIM) drive has been developed with predictive angle control technique. The classical PTC of induction motor drive involves direct control of torque and flux. The combination of direct torque control (DTC) with model predictive control (MPC) offers all the features of classical DTC and in addition it is easily implementable for MLI fed induction motor drives. This article introduces predictive angle control strategy for MLI fed OEWIM drive to reduce torque ripple, where as the classical PTC algorithm uses magnitudes of torque and flux. The proposed algorithm is developed by controlling the angle between stator flux and stator current, the voltage space vectors of MLI fed OEWIM drive are classified according to operating frequency range. The proposed PTC algorithm requires same computational time as that of classical PTC. The proposed algorithms are verified through simulation and experimental studies.

基于预测角控制的多电平逆变式开端绕组感应电机驱动的增强预测转矩控制

摘要 在本文中，多电平逆变 (MLI) 馈电开放式绕组感应电机 (OEWIM) 驱动的预测转矩控制 (PTC) 已开发与预测角度控制技术。感应电机驱动的经典 PTC 涉及转矩和磁通的直接控制。直接转矩控制 (DTC) 与模型预测控制 (MPC) 的组合提供了经典 DTC 的所有功能，此外，它还可以轻松实现用于 MLI 馈电感应电机驱动器。本文介绍了 MLI 馈电 OEWIM 驱动器的预测角度控制策略，以减少转矩脉动，而经典 PTC 算法使用转矩和磁通的大小。所提出的算法是通过控制定子磁通和定子电流之间的角度来开发的，MLI 馈电 OEWIM 驱动器的电压空间矢量根据工作频率范围进行分类。所提出的 PTC 算法需要与经典 PTC 相同的计算时间。通过仿真和实验研究验证了所提出的算法。
