This paper investigates the minimization of torque ripple in Permanent Magnet Synchronous Motor (PMSM) Drive using the Modified Model Predictive Torque Control (MMPTC) with multilevel inverters. The MMPTC grabs the good steady-state performance as of Model Predictive Current Control (MPCC) and provides direct torque control as in the Model Predictive Torque Control (MPTC). The MMPTC strategy also eliminates weighting factors in the cost function, unlike conventional Model Predictive Torque and Flux control (MPTFC). The torque ripple causes vibrations and noise and produces more heat loss in the drive, which leads to focus on the torque ripple reduction. Among the various torque ripple minimization approaches, the multilevel inverter configuration clutched more attention in electric drives due to rapid development in the semiconductor technology. Analysis of torque ripple behaviour of PMSM drive with MMPTC using two-level (2L), three-level (3L), and five-level (5L) inverters is carried out under different running conditions in MATLAB/SIMULINK software tools and also implemented in real-time with the help of dSPACE1104 controller.

本文研究了使用带有多级逆变器的改进模型预测转矩控制 (MMPTC) 来最小化永磁同步电机 (PMSM) 驱动器中的转矩脉动。MMPTC 具有模型预测电流控制 (MPCC) 的良好稳态性能，并提供模型预测转矩控制 (MPTC) 中的直接转矩控制。MMPTC 策略还消除了成本函数中的加权因素，这与传统的模型预测转矩和磁通控制 (MPTFC) 不同。转矩脉动会导致振动和噪音，并在驱动器中产生更多的热损失，这导致关注转矩脉动的降低。在各种转矩脉动最小化方法中，由于半导体技术的快速发展，多级逆变器配置在电力驱动中受到更多关注。
