“…Hysteresis in dampers is due to the difference between the accelerating and decelerating paths of the force-velocity curve [10], thus imposing a delay in the changes of internal pressures and ultimately forces. Therefore, we propose the nonlinear MR damping force (F MR ) approximated by a hyperbolic tangential function of the velocity and the displacement of the oscillator based on the papers [11,12]. In terms of mathematical expressions, the model makes use of a hyperbolic tangent function to represent the hysteresis and linear function to represent the viscous behaviour…”

A numerical study of an application of magnetorheological (MR) damper for semi-active control is presented in this paper. The damper is mounted in the suspension of a Duffing oscillator with an attached pendulum. The MR damper with properties modelled by a hysteretic loop, is applied in order to control of the system response. Two methods for the dynamics control in the closed-loop algorithm based on the amplitude and velocity of the pendulum and the impulse on-off activation of MR damper are proposed. These concepts allow the system maintaining on a desirable attractor or, if necessary, to change a position from one attractor to another. Additionally, the detailed bifurcation analysis of the influence of MR damping on the number of periodic solutions and their stability is shown by continuation method. The influence of MR damping on the chaotic behavior is studied, as well.

“…Here, counteract the force-offset problem for a single damper, a differential configuration of two identical dampers is used, as described in [13,14]. Accordingly, the damper force generated by j th MR damper is given by Note that according to the proposed differential configuration, the damper displacements are opposite in sign, that is…”

“…We next consider a ten-storey building model embedded with one pair of identical dampers to be placed on the first storey, with the parameters of the dampers given in [13]. Here, the building model has following structural parameters: Table II for the case no control and with this controller (b).…”

This paper presents an efficient control strategy for magnetorheological (MR) dampers embedded in building structures to mitigate quake-induced vibrations. In this work, MR dampers are used as semi-active devices, taking the advantages of the fail-safe operation and low power requirement. By using a static hysteresis model for the MR damper, a suitable controller is proposed here for direct control of the supply currents of the MR dampers using feedback linearization. The dampers are configured in a differential mode to counteract the force-offset problem from the use of a single damper. The effectiveness of the proposed technique is verified in simulation by using a ten-storey building model subject to quake-like excitations.
