Assuming a discrete time form for the system model, a polynomial Nonlinear Autoregressive exogenous (NARX) with a linear-inparameter model structure is selected in this work. Real-time data obtained using a computerbased data acquisition system from a 2.0L automotive diesel engine test-bed unit is used for parameter estimation. The orthogonal least squares (OLS) algorithm together with the Error Reduction Ratio (ERR) criteria are used to select the significant terms in the NARX models in order to determine a parsimonious model and estimate the parameters of nonlinear model. Finally, the models are validated by plotting the output predicted by the models and comparing it with the measured output. The modelling error of both models is examined. 2014-05-22T09:38:49Z 2014-05-22T09:38:49Z 2013 Article International Review of Mechanical Engineering, vol. 7(1), 2013, pages 46-52 1970-8734 http://www.praiseworthyprize.org/latest_issues/IREME-latest/IREME_vol_7_n_1.html http://dspace.unimap.edu.my:80/dspace/handle/123456789/34655 en Praise Worthy Prize S.r.l. |
