概要

In this paper we design a gain-scheduled (GS) H_∞ controller of a semi-active seismic isolation system using a large-scale 40kN-class magneto-rheological fluid (MR) damper for a multi-degree-of-freedom structure. By introducing a fictitious damper model we can transform the bilinear model into a linear parameter varying (LPV) model for which designing of a GS controller based on linear matrix inequalities (LMIs) is available. For verification of the control performance we carry out simulations and shaking table tests for some kind of earthquakes using the 40 kN-class MR damper. In comparison with a passive damper it is verified that the proposed method has good performance.
