Abstract—Magnetorheological fluids (MRF) are considered as smart material since the behavior of the fluid is interrelated with external magnetic field. The rheological behavior of the fluids is changed whenever the strength of magnetic field changed. One of the applications of MRF is Magnetorheological damper (MRD), a damper that can be controlled by magnetic field. Analytical model of the damper is important in order to understand the performance of MRD. Different types of model that depend on defined parameters were introduced by previous researchers, and investigation on those parameters is crucial to acquire a model with least value of error. A technique called nonlinear least squares fitting method is utilized in order to obtain those parameters. This study investigated five different MRD models and presents the result for parameter estimation for each model as a function of input current.
