Resumo
This paper shows how the sample rate and discretization methods affect the parameter identifica- tion of a NARX model, when applied to systems with hysteresis, whose is a model non-linear behavior usually found in electromagnetic devices. A Bouc-Wen model for a magneto-rheological damper is used as a system to be identified by a NARX model, considering the above mentioned scenario and a least-square based technique is used in this work to estimate model parameters.
