In recent years, the danger of relatively long period seismic waves is pointed out from the response of the skyscraper, and the sloshing damage of a large-sized tank in case of an earthquake. Generally, although a natural period is set as about 3 seconds by the isolation system, if a relatively long period seismic wave is taken into consideration, natural period need to extended further. Therefore we propose the super-long-period active isolation system that used active control aiming at the period of isolation system is extended, and the further improvement of isolation system performance. In this paper, we designed a control system, and selected the optimum variables of transfer function using genetic algorithm.
