<p>PURPOSE: An apparatus and a method for detecting rotor position for a switched reluctance drive are provided to achieve a robust and cost-effective method of monitoring rotor position and a rotor position detector. CONSTITUTION: A method of detecting rotor position comprises a step of deriving a value for flux linkage associated with the at least one phase of the machine at a first point, at a moment at which voltage is applied to that phase, a step of deriving a value of phase current and phase flux linkage at a subsequent point, a step of combining the derived flux linkage values to give a value of total flux linkage at the subsequent point, and a step of deriving the rotor position from the phase current and the value of the total flux linkage.</p> |
