This paper presents a method of indirect position estimation for three-phase switched reluctance machines suitable for starting and lower speed operation. Rotor position estimation is accomplished by injecting a pulse current whose amplitude is compared with two different thresholds. The rotor position of the three-phase SRM is identified in terms of six sectors for one electrical revolution of the...
A so-called bridged-T controller, which combines both open-loop and closed-loop control components is proposed for speed control of a switched reluctance motor. The open-loop controller provides a fast dynamic response and the closed-loop controller assures zero steady-state speed error by feedback of the error between the ideal open-loop response and the actual machine response. The bridged-T controller...
