Evaluation of a software configurable digital controller for the permanent magnet synchronous motor using field-oriented control

Abstract

This paper presents a software-defined digital controller for the permanent magnet brushless dc motor using field-oriented control (FOC). The proposed controller that improves the system performance in low torque ripple, and high efficiency is introduced and discussed in detail. The proposed FOC controller is implemented with a MC73110 motor control chip for experimental verification under 400W and 9,160rpm. The experimental motor waveforms and torque ripples with different commutation methods are investigated.
