Abstract :
A Magneto-Rheological (MR) damper exhibits a hysteretic and non-linear behavior. This behavior makes it a challenge to develop a model for the system. The present research is centered on proposing and analyzing a fuzzy-based method employed to introduce the electric current dependency into MR damper models, based on experimental data. Among the state of the art, a semi-phenomenological model was selected. The fuzzy-based method was compared against other approaches. The results showed that the fuzzy-based method was able to correctly introduce the dependency of the model to the electric current and reduce the prediction error by more than 12%.
