Hysteresis Modeling in MR Dampers

2021 22nd International Carpathian Control Conference (ICCC), 2021
Magnetorheological dampers are known to exhibit non-linear hysteretic behaviour. The source of the mechanism is due to the compressible nature of the fluid as well as the magnetic hysteresis of the ferromagnetic materials constituting the control circuit of the actuator. In this study the authors reveal a lumped parameter model of the actuator based on

MR-damper based control system

2009 IEEE International Conference on Systems, Man and Cybernetics, 2009
The precise variation of the magneto-rhelogical (MR) damping force in a semi-active suspension is a key issue in order to assure the desired performances over a suspension control system. The open loop control of this force is a very common strategy. Other schemes propose adaptive controller alternatives while the automotive hardware is a constrained ...

Adaptive control of structures with MR damper

2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC), 2009
In 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.

Design of experiments for MR damper modelling

2009 International Joint Conference on Neural Networks, 2009
An 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 ...

The Neuro-fuzzy Identification of MR Damper

2009 Sixth International Conference on Fuzzy Systems and Knowledge Discovery, 2009
It 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.

Gain scheduling for semiactive MR dampers

2012 American Control Conference (ACC), 2012
Control 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, 2006
In 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.

Characterization analysis of a MR damper

Smart Materials and Structures, 2014
In 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.
