Experiments with Feedback Control of an ER Vibration Damper

It is now becoming well-established that there is enormous potential for the application of smart fluids to a variety of problems in vibration control. In the development of materials and devices emphasis has been placed upon electro-rheological (ER) fluids which consist of a suspension of micron-sized, semiconducting particles in a dielectric base liquid. The application of an electric field of sufficient intensity causes a rapid (and reversible) increase in the ER fluid’s resistance to flow. A 1996 survey paper  explained the fundamental operating principles of ER fluids and described the possible modes of operation. However the main purpose of the paper was to review applications of ER fluids to vibration control.
