| Research Abstract |
This research aimed at control system design for shaking tables to improve the reproducibility of long-period earthquake acceleration waveforms. In the shaking table system to generate the long-period earthquake waveforms, the nonlinearities and lower resonant vibrations of hydraulic systems cause the deteriorations of the reproducibility of acceleration waveforms. In this research, at first, we constructed the precise simulators to analyze the shaking table motion. Then, we developed the control methodologies to compensate for the nonlinearities, resonant vibrations, and the effects of interference between actuators. The proposed control systems have been verified by experiments using a laboratory experimental setup.
