中文摘要:
      模糊控制应用在斜拉索-MR阻尼器振动控制时,可直接通过系统的响应得到MR阻尼器的输入电压,简单实用,不过需要大量调试才能得到系统响应的量化因子,工作量较大.在基于MR阻尼器斜拉索参数共振模糊半主动控制的基础上,提出一种改进的方法,使得模糊控制计算更加智能.以红水河特大桥的M22和M13拉索为研究对象,对其参数共振进行振动控制研究.结果表明:改进的基于MR阻尼器斜拉索参数共振模糊控制方法相比一般模糊控制方法更加智能,不需要斜拉索无控制时的响应可确定输入变量或输出变量的基本论域和量化因子且采用改进的模糊半主动控制方法进行振动控制时,阻尼器所需电压均小于一般模糊控制时所需电压.
英文摘要:
      The input voltage of the MR damper could be gotten directly by the response of the system, when the fuzzy semi-active control method was used for the vibration control of the cable-stayed bridge. An improved fuzzy semi-active control method, for parametric vibration of the cable-stayed with MR damper, was proposed, to make the fuzzy semi-active control method more smart. The parameter vibration control of the cable M22 and the cable M13 of the Hongshuihe cable-stayed Bridge was studied. The results show that the effect of the improved fuzzy semi-active control strategy is better than that of the fuzzy semi-active control strategy. In addition, the proposed fuzzy semi-active control strategy does not need to debug the scaling factor of input variables and output variables, and the MR damper requires lower voltages. Therefore,the proposed method makes the fuzzy control more intelligent.
