Learn about nonlinear system identification by walking through one of the many possible model options: A nonlinear ARX model. Brian Douglas covers the importance of adding an offset term to a linear model, adding nonlinear elements to the regressor vector, and adding a nonlinear combination of regressors. Explaining each of the components in a nonlinear ARX model should give you a basic understanding of nonlinear system identification.
