Application of neural network in real-time substructure testing with shaking table

Time delay is an important studying aspect in real-time substructure testing with shaking table.Time delay can affect accuracy and stability of a testing system,and even cause divergence of calculation results.In modern control theory,neural network is an effective way to compensate time delay.Here,it was used to predict a signal exerted on actuator of a shaking table.Through simulations,it was found that its effect of compensation on time delay is significant.
