DSP Based Research on the Sensorless Full-digital PMSM Drive System

Jian Zhang

Abstract

This paper introduces a digital sensorless control system based on TMS320LF2407 for permanent magnet synchronous motor. Rotor position and speed estimation algorithm as well as related error compensation algorithm are presented. It makes full use of the resources and characteristics of DSP. Experiment shows that it achieves good system indexes.
