Adaptive control of structures with MR damper
2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC), 2009In this study, an adaptive control scheme is designed for vibration isolation of SDOF structural system using a semi-active MR (magnetorheological) damper. The main goal of using a MR damper system is for structural protection against earthquake excitation and wind loading.

The Neuro-fuzzy Identification of MR Damper
2009 Sixth International Conference on Fuzzy Systems and Knowledge Discovery, 2009It is extremely difficult to describe the direct and inverse model of the Magneto-rheological (MR) damper, because an MR damper has strong nonlinearity between inputs and output. The paper presents a novel way to model these two models by using the universal approximation of neuro-fuzzy system.

Design of experiments for MR damper modelling
2009 International Joint Conference on Neural Networks, 2009An approach to find out the training inputs for identification of a Magneto-Rheological (MR) damper is proposed. Reduction of overuse of the damper, number of experiments and configurations of training inputs are main features of this approach. Experimental validation with a commercial MR damper was carried out.Main results show inputs configuration ...

Gain scheduling for semiactive MR dampers
2012 American Control Conference (ACC), 2012Control of semiactive devices, such as magnetorheo-logical fluid dampers for mitigating earthquake- and wind-induced motion of structures, is often accomplished using a clipped-optimal approach. This control strategy uses a primary optimal controller designed assuming the devices were active, linear and ideal, and a secondary bang-bang controller to ...

Series damper actuator system based on MR fluid damper
Robotica, 2006In our recent work, we have proposed a novel force control actuator system called series damper actuator (SDA). We have since built an SDA system based on magneto-rheological fluid (MR) damper. In this paper, the dynamics property of SDA system based on the MR fluid damper (SMRDA) is investigated.

2014
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 ...

Characterization analysis of a MR damper
Smart Materials and Structures, 2014In this paper, it is shown that the MR damper?s power dissipation capacity is determined by the time spent in the pre- and the post-yield damping regimes. This time is determined by its design, by the MR fluid?s rheological behavior and by the type of movement applied to the MR damper.

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.

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.

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
