A geometry based simplified analytical model of switched reluctance machines for real-time controller implementation

A geometry based simplified analytical model that decouples the current and position effect on flux and torque in the switched reluctance motor (SRM) drives is presented in this paper. This model gives a direct relation between phase current and torque accounting for the high degree of nonlinearity of the machine. A simple flux model and its inverse relationship have been developed to meet the diverse requirements of controller design. The paper emphasizes and demonstrates the importance of these relationships for real time controller implementation of high performance SRM drives.
