连续梁桥竖向振动半主动滑动模式控制研究
|
摘要
利用可变阻尼器对连续梁桥的竖向振动进行半主动控制,提出基于滑动模式理论的控制算法,并以实例加以说明。研究结果表明,滑动模式方法对控制系统溢出是不敏感的,具有较好的控制稳定性。通过实例仿真,这种控制方法能有效抑制连续梁桥的竖向振动,对桥梁结构的振动控制有重要的理论意义。
This paper is concerned with semi-active control of vertical vibration for continuous beam by variable dampers and puts forward the semi-active control law based on the sliding mode theory. Such an approach is intensive to the spillover problem encountered in full-active system and has better robustness. As the simulating result shows that such control can reduce vertical vibration of continuous beam effectively. This algorithm has an important theoretical significance for vibration control of bridge structures.
