【摘要】 对六自由度振动台的自由度(DOF)控制技术作了详细分析,得出其闭环控制传递函数.并指出国内外现有的模拟地震振动台控制系统在不同试验试件特别是柔性试件的系统控制方面还无法在最少迭代次数下获得控制效果,其控制算法有待作进一步研究.更多还原

【Abstract】 In this paper,DOF control of 6-DOF seismic simulation system is introduced in detail,and the closed-loop transfer function is achieved.In conclusion,national and international seismic simulation control systems in being couldn’t get the best control effect with least iterative times for different specimen,especially for flexible specimen.So the control arithmetic of the control system should be improved.更多还原
