摘要
Abstract
Seismic simulation shaking table experiments are the effective method to evaluate the seismic performance of building models and reduce seismic damage,among which the high-precision reproduction of input vibration waveform is particularly crucial.In view of the many factors that affect the accuracy in the actual experiment,such as nonlinear factors in the process of driving signal transmission,errors caused by model simplification and dynamic changes of experimental interference,a compound control strategy combining model reference adaptive control and three-parameter control is proposed on the basis of the traditional three-parameter control method.An adaptive harmonic eliminator is introduced to solve the harmonic distortion problem of sinusoidal signal.Through modeling simulation and shaking table experiment,the effectiveness of the proposed control strategy in improving output signal tracking accuracy and reducing waveform distortion is verified.关键词
