| 中文摘要 |
| 考虑描述磁流变(MR)阻尼器力学行为的LuGre动态摩擦模型, 建立了新的斜拉索–MR阻尼器系统模型, 该模型能够很好地描述斜拉索–阻尼器系统的动态特性, 且能够实时辨识MR阻尼器内部参数. 对于新的系统模型, 基于Lyapunov直接法设计了抑制斜拉索振动的半主动自适应控制方法; 原系统可变换为带有小参数的奇摄动系统, 采用奇摄动理论对该系统进行分析, 得到了另一类半主动自适应控制方法. 仿真结果表明提出的两种控制方法均能够很好地抑制拉索振动. |
| 英文摘要 |
| Using the LuGre dynamic friction model to describe the magneto-rheological damper behavior, we establish a new model for the cable-magneto-rheological(MR) damper system. The resulting model provides a good description of system dynamic characteristics; the parameters of the magneto rheological damper can be easily identified in real-time. Firstly, for the new model of cable-damper system, a semi-active adaptive control law is derived to suppress the vibration of stay cables; and the controller design is achieved using Lyapunov direct method. Secondly, a singular perturbation analysis allows reducing the new model to obtain another semi-active adaptive control law. The analysis of numerical simulations shows that the proposed control laws can effectively mitigate the vibration of stay cables. |
