“…[5] The identification system is a fairly mature field that has seen an interesting development and various contributions over the years, that we could not all include in this work, but just a few references that dealt with a parametric models which are ARX, ARMAX, OE and BJ. [9][10][11][12] Many works has been accomplished at this level, however, there's a number of issues in industry, which have not been satisfactorily dealt [4]. In previous study, we proposed "black box" modeling of a production line with three machines from the observed inputs and outputs, using ARX and ARMAX models.…”
