Identification of Hammerstein model with VRFT in the virtual two-degree of freedom control system

In this paper, we provide one of the identification methods of a system with Hammerstein typed nonlinearity in the closed loop. The basic strategy proposed here is to use the controller parameter tuning scheme in the virtual two-degree of freedom control structure. The proposed method enables us to obtain the parameters of a Hammerstein typed nonlinear system with one-shot experiment and an off-line optimization. In order to validity of our proposed method, we show a simple numerical example.
