Abstract
A magneto-rheological (MR) fluid damper is a semi-active control device that has recently begun to receive more attention
in the vibration control community. However, the inherent nonlinear nature of the MR fluid damper makes it challenging to
use this device to achieve high damping control system performance. The development of an accurate modeling method for a MR
fluid damper is necessary because of its unique characteristics. Our goal was to develop an alternative method for modeling
an MR fluid damper by using a self tuning fuzzy (STF) method based on neural technique. The behavior of the researched damper
is directly estimated through a fuzzy mapping system. To improve the accuracy of the STF model, a back propagation and a gradient
descent method are used to train online the fuzzy parameters to minimize the model error function. A series of simulations
were done to validate the effectiveness of the suggested modeling method when compared with the data measured from experiments
on a test rig with a researched MR fluid damper. Finally, modeling results show that the proposed STF interference system
trained online by using neural technique could describe well the behavior of the MR fluid damper without need of calculation
time for generating the model parameters
