Abstract

A large scale shaking table test has been carried out to confirm the efficacy of the gain-scheduled (GS) control theory. While the standard semi-active control algorithm induces a shock response by the rapid switching of controller, the proposed GS controller can avoid the problem by setting restrictions on the varying range of the system parameters. To apply the semi-active control we use developed damping device with the magneto-rheological (MR) fluid. Finally we got the response reduction of both the isolation layer and the upper structure.
