Hardware-in-the-loop simulation of bidirectional AC/DC converter connected to DTC-SVM for enhanced control of PMSM

Abstract

This thesis explores the application of hardware-in-the-loop (HIL) simulation to enhance the control of Permanent Magnet Synchronous Machines (PMSMs) by integrating a bidirectional AC/DC converter with a Direct Torque Control-Space Vector Modulation (DTC-SVM) scheme. The bidirectional converter enables energy transfer between the PMSM and the power grid during both inverter mode and rectifier mode. The DTC-SVM algorithm provides precise torque and flux control with reduced ripple. The proposed HIL setup combines a real-time digital simulator with a physical PMSM and bidirectional converter, allowing for comprehensive testing and validation of the control system. The experiments conducted demonstrate the effectiveness of the integrated system in achieving enhanced control of PMSMs and offer insights into parameter optimization and system performance under various operating conditions. The findings contribute to the advancement of PMSM control techniques and the development of HIL simulation methodologies for power electronic systems, promoting improved performance and reliability in industrial applications.
