This paper deals with the theoretical framework definition and the experimental application of the Hammerstein identification and related robust control technique to a quadratic DC-DC single switch boost converter. A set of 4th order transfer functions has been identified with the Hammerstein approach, on the basis of a PRBS excitation signal. The set of identified transfer functions has been then used to design a suitable robust control technique, able to properly deals with converter's parameters uncertainty and load variation. The proposed approach has been tested in numerical simulation and validated experimentally on suitably developed test set-up. It has been further compared with a classic PI controller.
