Abstract

Permanent magnet synchronous motors are widely used in industry, household and especially in the field of electric vehicles. Research on speed sensorless control for PMSM is an important part of synchronous motor drive research. Because the speed sensorless drive with new control algorithms has many advantages compared with the permanent magnet synchronous motor speed sensor drive such as: compact size, economical cost and high reliability. This paper presents the sensorless direct torque control for PMSM, with motor speed is estimated using MRAS method. Matlab/simulink software is used to simulate sensorless DTC drive for PMSM. The simulation results have shown that: the estimated speed tracking real speed and reference speed with small error.
