Abstract
Disclosed here is a speed control apparatus for a switched reluctance motor (SRM) including: a current control unit generating command currents for each period; a driving unit generating a pulse width modulation (PWM) signal to allow a voltage to be applied to the SRM; a magnetic flux error calculating unit calculating a magnetic flux error; a rotor position estimating unit calculating an estimation position using the magnetic flux error to output the estimation position to the magnetic flux error calculating unit; and a mode change-over unit allowing a command position corresponding to a command speed to be input to the magnetic flux error calculating unit.
