Performance Enhancement of Permanent Magnet Synchronous Motor Employing Iterative Learning Controller with Space Vector Pulse Width Modulation

Abstract

The PMSM generates the magnetic flux on its own as the rotor has permanent magnet and thus the motor never depend on any exterior source. The torque and speed ripples are the some of the disadvantages which affect the performance of drive. This paper proposes the performance enhancement of PMSM employing ILC and SVPWM driven by FOC to reduce both the speed and torque ripple. The result is compared with conventional PI controller. The outcome shows the reduction in torque and speed ripple which enhances the drive performance by using the above technique. The hardware result is obtained from DSP controller.
