Implementation of DTC-Controlled PMSM Driven By A Matrix Converter

Abstract

This paper deals with implementation of direct torque control (DTC) Permanent-Magnet Synchronous Motor (PMSM) driven by a matrix converter for industry applications. A field oriented vector & direct torque control (DTC) is implemented. The simulation test results are presented for converters with Space vector modulation techniques. The advantages of all solutions are indicated. The main focus is given to the drive control in the low speed range and to present drive systems with a matrix converter as an optimum solution for Industry Applications for precision control of speed and torque. The Simulation results of the novel scheme is carried out by using Matlab. The simulation results show that the proposed novel control scheme has a good dynamic response in terms of three phase stator current, speed and torque response. It can also reduce the torque ripple and THD of voltage and current gives better motor performance.
