Controller evaluation technique using virtual test model in shaking table

In control system design for shaking tables, it is well known that many times and kinds of experiments have to be done to find a suitable controller. However, the control experiments with the test model on the shaking table is sometimes very difficult to implement especially for large shaking table such as E-Defense, because it costs very much for constructing and installing the test model on the shaking table. If the test model dynamics can be taken into consideration without using real test model in the experiments, these experiments cost much less than the experiments with real test model. In this study, a controller evaluation technique is proposed using a virtual test model instead of using a real test model. By using the virtual test model, it is possible to evaluate control performance when the test model is equipped on the shaking table, without using the real test model.
