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.

Damper modeling for dynamic simulation of a large bus with MR damper
International Journal of Automotive Technology, 2011In this study, a large bus is tested to measure its dynamic response by the single-lane change test and the rapid stop test. A full car model is established by ADAMS/Car for computer simulation. For multibody modeling of a large bus, user-defined templates are used in the simulation.

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 ...

This chapter discusses some aspects of power drivers for MR dampers based on pulse-width modulation (PWM) amplifiers. These digital devices are inexpensive to make when using modern module-based switching circuitry, offer significant benefits in terms of lower power consumption and have been widely used within the automotive industry.

Adaptive identification of MR damper for vibration control
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004Magnetorheological (MR) damper is a promising semi-active device for vibration control of structures. This paper presents a simple mathematical model of MR damper with a small number of model parameters, which can express its hysteresis behavior of nonlinear dynamic friction mechanism of the MR fluid.
