摘 要:现行主动控制时滞补偿方法大多能实现小时滞补偿,但大时滞下算法有效性尚待试验检验。针对结构-AMD(Active Mass Damper)控制系统,采用经典Taylor一阶和Smith预估2种时滞补偿算法进行不同时滞下的补偿效果仿真分析,并利用3条地震波的位移和加速度的平均均方值和峰值作为时滞补偿效果指标;搭建拟动力试验平台对大时滞下补偿算法有效性进行试验研究。研究结果表明:通过理想状态下仿真和试验数据的吻合度较高验证拟动力试验平台搭建有效;与Smith预估时滞补偿算法相比,在大时滞100ms工况下采用Taylor一阶时滞补偿算法依旧具有较好补偿效果。Most of the current time delay compensation methods of active mass damper can realize the smaller time delay compensation,but the effectiveness of large time delay is yet to be verified by experiment.Based on the structure-AMD(Active Mass Damper)control system,two delay compensation algorithms,the classical Taylor first-order as well as Smith prediction,were used to simulate and analyze the compensation effect under different delays.The average mean square value and peak value of displacement and acceleration of three seismic waves are used as the delay compensation effect index.It built a Pseudo-dynamic Test platform to verify the effectiveness of the compensation algorithm under large time delays.The results of research show that:the pseudo dynamic test platform is effective through the high coincidence between the simulation and test data in the ideal state;the Taylor first-order delay compensation algorithm still has a better compensation effect under the large delay condition of 10Oms,which is compared with the Smith predictivedelay compensation algorithm.
