Abstract

This paper is dedicated to issue of approximation of nonlinear functions and nonlinear dynamical systems by Piecewise Affine (PWA) linear model. The article presents new identification Matlab toolbox for modelling and simulation of nonlinear systems. Functions of the toolbox together with GUI application simplified and accelerates identification of so called PWA OAF model. Identification of nonlinear systems is based on novel method of PWA modelling by generalized Fourier series. The approach provides identification of nonlinear functions of an arbitrary number of variables and identification of nonlinear dynamical systems in ARX model structure fashion from input-output data.
