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 subsequent estimate of rotor position. The method works robustly regardless of whether the current is continuous or is discontinuous.
