We have developed an efficient active control method. Its actuators are linear induction motors. The program developed in the present research can treat the limit of the actuators explicitly : the limit of the power and the time delay. Consequently, the new method works normally even under the extremely large amplitude of seismic vibration. We examined very carefully the performances and the reliability of each of the individual part of the physical model : the sensing or measuring unit, the data processing unit and the driving unit.In the process of the examination of the system, it was found that the high precision control technology of the actuators was promptly applicable to the active remote sensing of the ground based upon the artificial seismic sources. As an extension of the objectives of the present reseach, we investigated torsional vibration. Its feasibility was also examined.

我们已经开发了一种有效的主动控制方法。它的驱动器是线性感应电机。本研究所开发的程序可以明确地处理执行器的极限：功率和时间延迟的限制。结果表明，该方法在极高的地震动幅值下也能正常工作。对物理模型中的传感或测量单元、数据处理单元和驱动单元的性能和可靠性进行了仔细的检验，在检验过程中发现，高精度的驱动器控制技术可迅速应用于基于人工震源的地面主动遥感。作为本研究目标的延伸，我们研究了扭转振动。还审查了其可行性。
