Abstract
A position sensor emulator system and method for use in the control of synchronous machines are disclosed. The position sensor emulator system (220) includes a first bandpass filter (222) that filters phase voltage signals from a stator of a synchronous machine (230). A converter (224) that converts the filtered phase voltages into balanced two-phase quadrature signals. A rectifier (226) that rectifies exciter voltage signals of the synchronous machine (230) and a second bandpass filter (228) that filters the rectified exciter voltage signals to generate a reference signal.
