An improved shaking-table control method that can compensate the reaction force caused by a non-linear specimen in real-time has been 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 according to the estimated results. Because the identification and compensation are repeated in a short time, table acceleration can be accurately controlled even when the characteristics of the specimen vary dynamically during the excitation. The scheme to decide the controller parameters (the sampling frequency and the order of the filter, etc.) is also described. The shaking-table excitation compensated by the adaptive filter were simulated. And it was found that the filter effectively compensates the reaction force.
