For aiming the completion of 2005, 3-D Full-Scale Earthquake Testing Facility is now under construction in Miki city, on the north of Kobe city. The basic performances of this facility are the maximum velocity of 200 cm/s and the maximum displacement of 200 cm p-p in the horizontal excitation with the test weight of 1200 ton. Although, the developments of the servo valves, actuators, etc. are progressing in order to realize above performances, there is no appropriate analytical model for simulation and control system design. The object of this study is to find the effective linear analytical model and control algorithm for the 3-D Large-Scale Shaking Table.
