Abstract

A new control method for a shaking table-which compensates the reaction force caused by a non-linear specimen in real-time was previously developed. This method estimates the error in the transfer function by using the recursive least-square method, then the error is compensated by an adaptive filter. Verification tests with a large-scale shaking table controlled by this method were carried out in the present work. Even when the characteristics of the specimen change during excitation, the desired pseudo-velocity response spectra of the table acceleration which is three dimensional artificial earthquake wave can be achieved with the adaptive filter. The results of these tests show the effectiveness of this method.
