  • Publication number: 20140184131
    Abstract: Disclosed herein are a method and apparatus of controlling a switched reluctance motor (SRM). The method of controlling driving of an SRM, the method includes: sensing a variation of a load of the SRM; and controlling both of a dwell angle and a PWM duty ratio of the SRM according to the variation of the load of the SRM. Therefore, an angle and a current are simultaneously controlled, thereby making it possible to decrease a torque ripple at a low speed and constantly control a torque and rapidly respond to a command speed at a high speed. In addition, a speed and a torque of the SRM may be more precisely controlled.
