As a main test equipment for seismic study,the shaking table was fast developed in the past forty years,from linear to nonlinear,from time-invariant to time-varying,from analog control to digital control,and from displacement control to acceleration advanced control.The development and current situation in shaking table control system are presented from three aspects,including mode method,parameter identification and control algorithm.And then,the developing trends of shaking table control system are proposed,which include study of specimen-table coupling model,accurate parameter identification,parameter self-tuning,advanced nonlinear control algorithm and multiple-shaking table-array control system.
