Design and Implementation of Direct Torque Control of IPMSM Drive using Three-Level Inverter and FPGA for Electric Vehicle

This study introduces the design and implementation for Direct Torque Control (DTC) of Field Programmable Gate Array (FPGA) based Interior Permanent Magnet Synchronous Motor (IPMSM) with Space Vector Pulse Width Modulation (SVPWM) configuration inverter for Electrical Vehicle (EV). In contrast to conventional DTC, a new DTC algorithm of drive system is proposed that endowed unified torque/flux responses with precise control levels of multiple voltage vectors. The proposed drive unified inverter states for obtaining faster dynamic torque. Consequently, the DTC scheme inspected with suppresses steady state torque ripples. The main design features of the IPMSM drive are self-regulated flux and hardware implementation for EV. The comparative analysis is made between the Simulink and real time results. Further, the ripple content of torque and flux of proposed real time of the drive is examined numerically with Simulink drive that an average ripple minimization of 60% for torque flux under load conditions is found that is achieved by FPGA. Therefore, the obtained experimental results clearly show the significance of the FPGA platform that the drive attained precise and effective torque control in both steady and dynamic conditions for EV. The DTC ensures efficiently controlled vehicles. This paper represents the proposed control methods that ensure both safety and stability in EV using DTC. This paper summarizes how the new DTC technique effectively reduces flux and torque ripples through FPGA control.
