Paper Abstract

Two control techniques are explored analytically for a dynamic vibration absorber with a magnetorheological fluid damper replacing the absorber dashpot. The approaches include skyhook control and an approximation to a linear quadratic optimal control. The approximate-optimal control, which attempts to match the magnetorheological damper force to an optimal control force based on a linear absorber, is shown to improve the dymanic absorber performance over a substantial range of excitation frequencies and force levels, while the skyhook approach is less successful. Detuning the absorber natural frequency below the optimal detuning for a linear absorber improves performance in the approximate- optimal case.
