【Abstract】 In order to improve the reproduction accuracy of seismic wave signal of shaking table, combined with virtual instrument and iterative learning control algorithm with forgetting factor, the iterative learning control system of shaking table was designed to improve the reproduction accuracy at the same time.It realizes many functions, such as power spectrum estimation, data synchronous acquisition, data storage, report, waveform correlation estimation and so on.The measured recurrence results of Guangyuan Shijing seismic wave table show that the system has realized the corresponding function, the operation effect is good, and the recurrence accuracy is more than 95%.更多还原
