In recent years, the relatively long period seismic waves have been observed in the various earthquakes, and the resonances of the high-rise buildings during earthquakes have been reported around the same time. Usually, the natural period of the isolation system is about 3 seconds, but it needed to be extended. Therefore we propose a super-long-period active seismic isolation system as a method for extending the natural period. In this paper, we designed a control system for it using the model-matching-method, and selected the optimum variables of transfer function using genetic algorithm.
