Experimental Study on Shaking Table Control Using Adaptive Control

The full-scale earthquake testing facility (large-scale shaking table), which is now being constructed by the Japanese government, requires stable and precise control for conducting satisfactory dynamical fracturing tests of structure model. We had ended the experimental study of enhancing control by using a small-scale shaking table, and then started the experimental study of enhancing control by using a medium-scale shaking table. A final goal of the series of the study is to obtain a guideline of enhancing control for the experiment by using the large-scale shaking table. In this paper, the Minimal Control Synthesis (MCS) is applied to a shaking table-test control. The MCS has been implemented in the controller design for the experiments of the small-scale and the medium-scale shaking table and proved to be effective for enhancing shaking table control by the experiments. This paper reports the results of the control experiments.
