In this chapter, the authors present a review of MR damper structures and MR valve configurations. The structures are described in terms of the arrangement of cylinders and the MR valve topologies. The range of examined valve structures involves a conventional standard single-coil and single-gap (annulus) piston as well as multiple coil assemblies ...

Comparison of MR damper models
18th Mediterranean Conference on Control and Automation, MED'10, 2010A Magneto-Rheologial (MR) damper exhibits a hysteretic and non-linear behavior. This behavior makes it a challenge to develop a model for the system. The present research is centered on analyzing and comparing three state-of-the-art models for MR dampers. NARX, Semi-Phenomenological, and Phenomenological models were selected.

Efficient Modeling of MR Dampers
IEEE Latin America Transactions, 2014The Magneto-Rheological (MR) dampers are devices that use a MR fluid that can quickly change their rheological properties if a magnetic field is applied. Being part of an automotive suspension (semi-active ) can dissipate energy in a controlled manner, which has important benefits as comfort, road holding, safety, etc. The modeling of MR dampers allows

Energy-harvesting dampers have received a great deal of attention since the early 1990s. An attractive feature of these dampers is their ability to recover kinetic energy normally dissipated by conventional dampers. In this chapter the authors are concerned with an energy-harvesting device which comprises three main components: an MR damper, a power ...

IMC-based control system on a MR damper
2009 European Control Conference (ECC), 2009A control system of a Magneto-Rheological (MR) damper force based on the Internal Model Control (IMC) strategy is proposed. Dynamic models of the MR damper were built exploiting Artificial Neural Networks (ANN). The control system was implemented with a controller based on an inverse ANN model of the MR damper and a forward model as internal nominal ...

Blind Hammerstein Identification for MR Damper Modeling
2007 American Control Conference, 2007This paper proposes a new blind approach to identification of Hammerstein systems, where a static nonlinearity precedes a linear dynamic system. By exploiting input's piece-wise constant property, the denominator of the linear system is identified first together with the order and time delay.

DESIGN AND CHARACTERIZATION OF MR DAMPER
Advanced Nondestructive Evaluation II, 2008Three kinds of MR damper, such as valve mode type, direct-shear mode type and squeeze mode type are applied in engineering field. In this paper, a valve mode type MR prototype damper was designed and fabricated for experimental study. The circuit design of MR damper consisted with the bobbin, retainer and outer cylinder.

Modeling MR-dampers: the ridgenet estimation approach
Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002This paper develops a new technique, the ridgenet estimation, for the blackbox modeling of magnetorheological fluid (MR) dampers. It continues the original effort on wavelets-based identification and makes a step forward by employing the ridgelet network to construct the nonlinear mapping.

Modeling MR-dampers: a nonlinear blackbox approach
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001The focus of this paper is on the application of nonlinear blackbox identification techniques to the modeling of magnetorheological fluid dampers (MRD), a new family of devices devoted to solving a wide range of structural control problems. In the following, we first give in Section 1 a brief introduction to the current status and practice in civil ...
