| Research Abstract |
Switched Reluctance Motor (SRM), as a reliable, low-cost motor without rare earth, its application to electric vehicles is expected. However, large torque ripple and rotor position sensor have drawbacks such as compromising the reliability and low cost. In this study, in order to overcome the drawbacks of these two, we demonstrate high-precision sensorless torque control of automotive SRM.
