MR dampers are complex nonlinear devices whose force-velocity response is hysteretic. Several models have been developed that approximately recreate this behavior. In vibration mitigation systems that make use of MR dampers, it is necessary the implementation on nonlinear control techniques to account for the damper nonlinearities. A case study is presented in this paper in which a base-isolated building containing an MR damper is to be stabilized during a seismic motion. For this purpose, a backstepping controller is designed. The controller performance is evaluated by means of numerical simulations. Some observations about backstepping control experimentation are also made.
