This paper presents a practical control methodology of shaking tables for earthquake simulators. Reaction force generated by a specimen on the shaking table generally deteriorates the motion performance of the table, resulting in the lower control accuracy of seismic tests. Especially, in cases of excitation tests for structures (power facilities, large vehicles, etc.) including motors with periodic...
In this paper, we propose a precise short-span seeking control system based on the pivot friction compensation. The proposed compensator consists of the feed forward compensation with perfect tracking control method and feedback compensation with optimum friction compensation. The effectiveness of the proposed compensator is verified by using numerical simulation.
