... of sensors installed at strategic locations is designed and a bypass electrorheological (ER) damper is applied to achieve the best control effect more rapidly and accurately. The determination of sliding surface in terms of the Routh-Hurwitz stability criterion is combined with continuous controller design...

...Seung-Bok Choi, Professor; Sung-Ryong Hong, Graduate Assistant This paper presents two different types of electrorheological (ER) mounts that can support a static load of 200 kg. One is a flow mode type, and the other is a squeeze mode type. After analyzing the governing equations of motion, two ER...

...Kevin C. Poulin; Rimas Vaicaitis, Renwick Professor and Chair of Civil Engineering, A numerical study of the use of electrorheological (ER) fluids and piezoelectric (PZT) actuators to control random vibrations of stiffened composite panels is presented. Active control of stiffness and damping...
