Real time parameter determination in saturated inductors submitted to non-sinusoidal excitations

Parameter's determination on saturated systems is a complex task. Sometimes you can determine these parameters by calculation but building errors must be checked to verify the final values of them. You can use accurate off-line models but the time of process could be excessive for a factory process. In this paper we describe a recursive algorithm to calculate the parameters in real time and buried in a generic measurement system made to test three phase inductors.
