Current sensorless field oriented control of synchronous reluctance motor

Abstract

The authors propose and examine a control strategy for a synchronous reluctance motor which eliminates the need for a current sensor. Control strategies, practical implementation, and performance of a current sensorless field-oriented control for a synchronous reluctance motor are presented. A field-oriented control scheme without current sensors which includes a voltage reference calculator which generates the required voltage references from the torque command and the motor speed is proposed. Excellent control performance has been obtained, which indicates that current sensorless field-oriented control of synchronous reluctance motors can be applicable in practical high-performance drive systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
