This paper presents an implementation of a novel semi-active controller that uses only acceleration information, via a magnetorheorological damper, on a flexible structure. This controller was motivated by the scheme of a peak-detector system used on electronics circuits. That is, given a peak-detector system, we modify it to develop a novel semi-active controller. The experimental setup consisting of a two-story flexible structure, where the magnetorheorological damper is connected in a ‘semi’-brace connection, demonstrates an acceptable performance of our semi-active controller when it is compared with classical semi-active controllers. |
