摘要：
When a shaking-table of an earthquake simulator is driven for the seismic experiment of a specimen, its motion is affected by a reaction force caused by the specimen on the table. This paper presents a reaction force compensation methodology for shaking tables in earthquake simulators. This methodology is designed by using the RFC (Reaction Force Compensation) based on the disturbance observer method in real time. RFC observes the reaction force and compensates the observed reaction force by using a phase lead compensator. The effectiveness of the proposed technique is verified by using a two-dimensional large shaking table.
