Two-step data driven control design for shaking table affected by reaction force

The burden of control adjustment of shaking table is increasing with the background of lack of skilled operators. Adjustment of feed-back control is particularly difficult because the response of shaking table changes due to the reaction force of the specimen. The data-driven control is a promising approach to address this problem. We applied data-driven control to each of feed-back control for the reaction force compensator and feed forward control for the response improvement. We verified the effectiveness of the proposed method through numerical simulations.
