Abstract
A control for operating an inverter coupled to a switched reluctance machine includes a relative angle estimation circuit for estimating rotor angle for a phase in the switched reluctance machine. The relative angle estimation circuit estimates a phase voltage and thereby calculates phase flux linkage to estimate the rotor angle.
