Abstract EN
The main aim of this study is to handle the case where the structures of nonlinear systems are unknown.
In the many works, the parametric identification of nonlinear systems represented by Hammerstein model, with discontinuous and asymmetric nonlinearity, considers the structures of the nonlinear and linear blocks are known, especially the nonlinear bloc.
To solve this problem, a unified form of nonlinearity representing eight cases of nonlinearities can be used.
The parameters of both blocks, linear and nonlinear, are estimated using an iterative subspace approach.
More importantly, in an attempt to show the extent to which this method is efficient, we apply it to experimental data obtained from the electropneumatic system.
As a result, the numerical and experimental examples confirm a good conditioning and computational efficiency.
