设置AMD的铁路钢桥鲁棒控制研究
Research on robust control for steel railway bridges with AMD
摘要
Abstract
The robust control method for the vibration response of the railway steel bridge with active mass damper (AMD) under passing train load was studied. The controlled state equation and robust control method of the railway steel bridge with AMD system under the action of train load were established. Taking a railway steel bridge as engineering background,the integral shell model and lower-chord node entity submodel of the railway steel truss bridge were set up. The control effects of vibration response of the railway steel bridge with AMD system under the load of different speed train were compared by using uncontrol,LQR active control algorithm and robust control algorithm while a preliminary analysis of robust control effect for node maximum normal strain was carried out. The research results show that control effects of the displacement response and the node's maximum normal strain of the railway steel bridge with AMD while suffering different speed train load are obviously better than the LQR active control when using the robust control algorithm.关键词
