Abstract

System Identification of a system is the very first part in design control procedure of mechatronics system. There are several ways in which a system can be identified. An example of well known techniques are using time domain and frequency domain approach. This paper is focused on the fundamental aspect of system identification of mechatronics system in which it includes the step by step procedure on how to perform system identification. The system for this case is XY milling table ballscrew drive. Both parametric and nonparametric procedure. In addition, comparison of estimated model transfer function obtained via non-linear least square (NLLS) and Linear least square estimator algorithm were also being addressed. It shows that the NLLS technique perform better than LLS technique for this case. LLS technique for this case. The result was judged based on result was judged based on result was judged based on the requirement during model validation procedure such as through heuristic approach (graphical observation) of best fit model with respect to the frequency response function (FRF) of the system.
