This paper presents an adaptive control methodology of shaking table systems for earthquake simulators. In the system, reaction force generated by a specimen on the shaking table generally deteriorates the table motion performance, resulting in the lower control accuracy of seismic tests. In order to compensate for the reaction force and to provide the precise table motion, therefore, an adaptive...
This paper presents a novel initial value compensation (IVC) using an additional input for semi-closed control systems. The authors have already proposed the IVC approach using the additional input for residual vibration suppression in the fast and precise positioning control. In the approach, however, an essential subject has remained, i.e., the positioning control in the load side could not satisfy...
