چکیده
A Wiener system is composed of a linear dynamic subsystem followed by a static nonlinearity. It is well known in the literature that the identi cation of the linear subsystem of a Wiener system can be separated from that of the output nonlinearity, if the input signal is Gaussian. In order to deal with non Gaussian inputs, two new algorithms are proposed in this paper for direct identi cation of the linear susbsystem, regardless of any parameterization of the output nonlinearity. The essential assumption required in this paper is the strict monotonicity of the output nonlinearity.

Sliced Inverse Regression for the Identification of Dynamical Systems, Report no. LiTH-ISY-R-3031
The estimation of nonlinear functions can be challenging when the number of independent variables is high. This difficulty may, in certain cases, be reduced by first projecting the independent variables on a lower dimensional subspace before estimating the nonlinearity. In this paper, a statistical nonparametric dimension reduction method called sliced inverse regression is presented and a cons...
متن کاملMaximum Likelihood Identification of Wiener Models, Report no. LiTH-ISY-R-2902
The Wiener model is a block oriented model having a linear dynamic system followed by a static nonlinearity. The dominating approach to estimate the components of this model has been to minimize the error between the simulated and the measured outputs. We show that this will in general lead to biased estimates if there is other disturbances present than measurement noise. The implications of Bu...

متن کاملInverse Regression for the Wiener Class of Systems, Report no. LiTH-ISY-R-3032
The concept of inverse regression has turned out to be quite useful for dimension reduction in regression analysis problems. Using methods like sliced inverse regression (SIR) and directional regression (DR), some high-dimensional nonlinear regression problems can be turned into more tractable low-dimensional problems. Here, the usefulness of inverse regression for identification of nonlinear d...
متن کاملWiener-Hammerstein Benchmark , Report no. LiTH-ISY-R-2910
This paper describes a benchmark for nonlinear system identi cation. A Wiener-Hammerstein system is selected as test object. In such a structure there is no direct access to the static nonlinearity starting from the measured input/output, because it is sandwiched between two unknown dynamic systems. The signal-to-noise ratio of the measurements is quite high, which puts the focus of the benchma...
