ABSTRACT:
A switched reluctance drive is controlled without using a physical rotor position detector. The control method estimates the standing flux-linkage associated with the phase and uses this estimate to improve its estimate of rotor position. The method works robustly regardless of whether the current is continuous or discontinuous.
