Vector control and reliability improvement for a switched reluctance motor

This paper presents a vector control for a switched reluctance motor. The design, and implementation of a three phase, eight-pole, 10 HP switched reluctance motor with a vector control is described. Two different control algorithms which consist of a field oriented control, and a maximum torque control are discussed. Performance of the switched reluctance motor system is improved. In order to improve the reliability of the system, some control strategies are proposed. These strategies result in the torque of the motor being held constant while one leg of the inverter is opened or shorted. A theoretical analysis, and experimental results follow
