Mathematical Modeling and Speed Control of 6/4 Switched Reluctance Motor Drive

A mathematical model of a 6/4 Switched Reluctance Motor (SRM) is developed in this paper by considering the non-linear aligned and unaligned inductance profile of the motor. The transient response and ripple of the SRM motor are studied for various load conditions. A proportional-integral controller is used for controlling the speed of the motor and reducing the transients of the system. Torque-ripple minimization is effected by the inner loop hysteresis controller. MATLAB Simulink platform is used to develop the mathematical model and determine the performance of the 6/4 SRM in open and closed loop configurations with speed, current, and position feedback.
