Title: Identification of Discrete Time Nonlinear System described by Hammerstein Model: Application to a Thermal System
Authors: Abdessattar CHAARI, Khaled ELLEUCH, Maher KHARRAT and Samira KAMOUN
Abstract: In this paper, we are interested on parametric identification of a thermal system, in real time, which is described by a discrete non-linear Hammerstein model with unknown parameters. Based on the method of the prediction error and the technique of the Recursive Least Squares, the identification problem of the static nonlinear part and the dynamic linear one of the system is studied. The thermal system is constituted of a power amplifier, a bellows and a sensor. A unit of treatment and calculation with a data acquirement card is used for the identification process in real time. The experimental results illustrating the validation of the analytic method are presented and discussed.
