Control characteristics of SRM drives. Part II: operation in the saturated region

Part I of this two-part paper analyzed the control characteristics of switched reluctance motor (SRM) drives for operation of the motor in the linear region of its magnetic characteristics. This part completes the analysis, presenting the control characteristics in the saturated region. A description of the motor operation in the saturated region is first formulated. Then the control variables, the relationships between the motor torque and the control variables, and the torque capability are determined for both current-fed and voltage-fed SRM drives. The basic schemes for the speed control of a SRM are also presented
