Semiactive vibration suppression with electrorheological-fluid dampers

摘要

Semiactive vibration suppression with elemenrorheological (ER)-fluid variable dampers is proposed and demon- strated to be a robust approach to suppressing the vibration of space structures. The principal characteristics of an ER-fluid variable damper are measured, and a simple mathematical model of the damper is proposed. Based on the mathematical model of the damper, several semiactive on-off control laws are proposed.
