Abstract:
This paper presents a novel and simple model that describes the hysteretic force-velocity
relationship of Magneto-Rheological (MR) fluid dampers and proposes an approach for the
model parameter identification. The model is developed by using the curve fitting technique.
The MR damper hysteresis is represented as a mixture of sigmoidal and Gaussian functions,
resulting in a significant reduction of model parameters. The identification is conducted by
matching the simulated model output and experimental data while adjusting the model
parameters for a minimum root-mean-square matching error. The res'Lllts, compatible to the
widely-adopted Bouc-Wen model, show advantages in reducing the model complexity and
enabling a feasible control design for semi-active structural control with MR dampers.
