Position control of an 8/6 switched reluctance machine without current sensor

Abstract

The electrical motion drives are more and more used in various industrial processes. The choice of the motor drive is based on power, speed, precision, and cost requirements. There are many different types of motors for motion drives application. AC and DC motors feature brushed or brushless designs are suitable for a variety of industrial applications. Speed, torque and position control are the most used motion control systems. There are many papers about switched reluctance motor speed control and torque control but few about position control. This paper pretends to contribute for the potentiality of the switched reluctance motor in position application. In the first part it is presented the theoretical concepts for motor shaft position. The second part presents a prototype implementation and experimental results when intermediate position between two poles position alignment are reached.
