TLDR
In this article, an iterative method is proposed for the identification of nonlinear systems from samples of inputs and outputs in the presence of noise, which consists of a no-memory gain (of an assumed polynomial form) followed by a linear discrete system.Abstract:
An iterative method is proposed for the identification of nonlinear systems from samples of inputs and outputs in the presence of noise. The model used for the identification consists of a no-memory gain (of an assumed polynomial form) followed by a linear discrete system. The parameters of the pulse transfer function of the linear system and the coefficients of the polynomial non-linearity are alternately adjusted to minimize a mean square error criterion. Digital computer simulations are included to demonstrate the feasibility of the technique.read more

An Iterative Algorithm for the Subspace Identification of SISO Hammerstein Systems
TL;DR: In this article, an algorithm to identify state-space models for single input single output (SISO) Hammerstein structures based on input-output measurements is described, where the unknown parameters are then estimated using an iterative procedure that solves a least square problem at each step.
