Abstract
A substantially smooth, continuous and sinusoidal air gap flux signal for an AC machine is provided from machine terminal voltages and line currents. A voltage representative of the machine stator voltage is combined with a voltage representative of the resistive voltage drop component across the stator to yield an intermediate voltage. This intermediate voltage is integrated and combined with a voltage representative of the stator flux leakage reactance to yield an air gap flux signal proportional to the difference between the integral of the intermediate voltage and the stator flux leakage reactance voltage.
