Abstract :
This paper present the comparison of different model structure selection of ARX modelling using R2, MDL and AIC criterion. Input signal for the process is pseudo-random binary sequence (PRBS) and STEP response with a magnitude which vary from 0 to 5 volts. The comparisons have been made by considering the ACF and CCF validation technique. The results have shown that R2 provides superior model performance when model complexity is not considered as the penalty.
