In this paper a novel method for modelling and testing of electric drives is presented. Such method is based on auto-tune tests to identify an equivalent Hammerstein non linear model of the considered process. It represents a practical compromise in order to retain both a complex and accurate modelling and a solution as simple as possible for testing purposes. The above technique was tested experimentally in order to identify a drive constituted by a dc/ac inverter supplying a single-phase induction motor. Extensive simulations and experimental tests show that Hammerstein models can enlarge the range of allowable signal variations around a given operating point with respect to conventional linear modelling.

Abstract
In this paper a novel method for modelling and testing of electric drives is presented. Such method is based on auto-tune tests to identify an equivalent Hammerstein non linear model of the considered process. It represents a practical compromise in order to retain both a complex and accurate modelling and a solution as simple as possible for testing purposes. The above technique was tested experimentally in order to identify a drive constituted by a dc/ac inverter supplying a single-phase induction motor. Extensive simulations and experimental tests show that Hammerstein models can enlarge the range of allowable signal variations around a given operating point with respect to conventional linear modelling.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
