Experiment and modeling research on magneto-rheological damper
For the strong non-linear characteristics of magneto-rheological damper(MRD), building an effective model is a key to make MRD use in practical engineering. For both the parametric model and non-parametric model have their own drawbacks, this paper proposed a new model which combined the parametric model with non-parametric model. This new model uses an adaptive neural-fuzzy inference system(ANFIS) to build a non-parametric model describes the effect of displacement and velocity on damping force; use parametric method to describe the maximum damping force in relation with the voltage and the maximum rod speed. The results shows that this modeling method has a good approximation to the MRD experimental results, and can well reflect the non-linear characteristics of MRD. This method is convenient for actual control and shorten the calculation process.

Abstract：For the strong non-linear characteristics of magneto-rheological damper(MRD), building an effective model is a key to make MRD use in practical engineering. For both the parametric model and non-parametric model have their own drawbacks, this paper proposed a new model which combined the parametric model with non-parametric model. This new model uses an adaptive neural-fuzzy inference system(ANFIS) to build a non-parametric model describes the effect of displacement and velocity on damping force; use parametric method to describe the maximum damping force in relation with the voltage and the maximum rod speed. The results shows that this modeling method has a good approximation to the MRD experimental results, and can well reflect the non-linear characteristics of MRD. This method is convenient for actual control and shorten the calculation process.
