A Predictive Current Control Strategy for a Medium-Voltage Open-End Winding Machine Drive

Abstract

This paper presents a medium-voltage drive based on an open-end winding induction machine supplied by a multilevel power converter topology. The power converter consists of cascaded two-level three-phase voltage source inverters (VSI) connected to each side of the machine windings and each VSI is fed by an isolated DC supply. The topology has been previously reported in the literature as a sinusoidal pulse-width modulation operating in an open loop. In this work, a closed-loop model predictive control (MPC) strategy is proposed. MPC offers a much simpler method to control the power switches of the inverter compared to complex modulation strategies that are typically used in multilevel converters. Moreover, the advantage of reducing the common-mode voltage offered by the open-end winding configuration is fully exploited in this work. Simulation results are presented to validate the performance of the proposed topology and control method.

“…Notably, it has found successful applications in electromechanical systems in [24,25] and robotics in [26]. Recent literature as [27] introduces MPC solutions as for electric drive control, including current control in Induction machines [16,28,29], and even in the domain of brushless DC Motors with separate speed and current control [30]. Cascade MPC is commonly employed for speed control, enabling torque limitation to the maximum value while ensuring optimal dynamic performance [27,29].…”

Model Predictive Control Design and Hardware in the Loop Validation for an Electric Vehicle Powertrain Based on Induction Motors

“…Other authors [26] have performed a comparison of CCS-MPC with a conventional PI in a simulation that resulted in the better robustness of the MPC against a load disturbance. Some improvements in FCS-MPC have been achieved in [27,28], where partition optimization and a predictive strategy that reduced the common-mode voltage at the machine terminals were used, respectively. Others [29] have proposed an online virtual voltage vector synthesis strategy to solve the current error generated by FCS-MPC, verifying its effectiveness against ordinary FCS-MPC.…”

“…Others [29] have proposed an online virtual voltage vector synthesis strategy to solve the current error generated by FCS-MPC, verifying its effectiveness against ordinary FCS-MPC. Nevertheless, the researchers of [28] compared it with sinusoidal pulse width modulation (SPWM) and it could not achieve the low total harmonic distortion (THD) current and torque ripple values shown by the SPWM.…”
