Permanent Magnet Synchronous Motor Control System and Speed Sensorless Overview of the Control System

Abstract

In this paper, the current control strategy of permanent magnet synchronous motor (PMSM) is introduced and the advantages and disadvantages of each method are compared and analyzed. At the same time, from the angle of different speed of permanent magnet synchronous motor, the principle of position sensor less control algorithm is introduced, and the advantages and disadvantages of each algorithm are compared and analyzed.
