Comparative study of drive systems using vector-controlled PMSM fed by a matrix converter and a conventional frequency converter

Abstract

This paper presents a comparative study of a drive system with a permanent magnet synchronous motor fed by a matrix converter and a voltage source inverter with diode rectifier stage. A rotor-oriented vector control is implemented in the drive control. Space vector modulation techniques are used for both converters in the output current modulation process. Initial simulation test results and comparison are presented. The advantages of both solutions are indicated. Special attention is given to the drive control in the low speed range. The main aim of this article is to present drive systems with a matrix converter as an interesting alternative solution for automation systems for precision control of speed and position. The technological contribution of this study lies in its potential application to robotics.
