Lyapunov semi-active vibration control with an MR fluid actuator

An experimental study of a semiactive magneto-rheological fluid variable damper for vibration suppression of truss structures

“…However, when compared with the particle-dispersion type of ER fluid, MR fluids have superior properties in a much wider temperature range, typically −40 to 150 • C [9]. MR fluids have been used to develop vibration suppression devices [9][10][11][12]. Dyke et al [10] reported that a semiactive system using an MR damper is quite effective for seismic response reduction over a wide range of seismic excitations.…”

“…Dyke et al [10] reported that a semiactive system using an MR damper is quite effective for seismic response reduction over a wide range of seismic excitations. Lee et al [11] demonstrated the superior performance of Lyapunov semiactive vibration control with an MR fluid actuator. Tsuchiya et al [12] reported on an application study of MR fluids in a small variable-damping mount intended for precision equipment of automobiles, such as CD players.…”
