【摘要】 地震模拟振动台作为结构抗震研究重要的试验设备之一,从20世纪60年代至今,经历了从线性到非线性、时不变到时变、模拟控制到数字控制、位移控制到加速度高级算法控制的发展过程。本文从建模方法、参数识别和控制算法三个方面回顾了地震模拟振动台控制系统研究的发展历程与现状,并阐述了地震模拟振动台控制系统的发展趋势,即试件与台面动力耦合模型、高性能参数识别、控制器参数自整定、强非线性高级控制算法、振动台台阵系统控制算法。更多还原

【Abstract】 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.更多还原
