摘要
模糊振动控制中存在的模糊控制规则的建立大都依赖于主观经验的现状，对此本文提出了一种通过对结构振动模糊建模来产生控制规则的方法。首先，通过对系统运动状态变量的模糊化，建立结构振动的模糊关系模型；其次通过对结构振动的模糊关系模型的分析，提取出模糊控制规则；最后，通过一个单自由度体系的数值仿真对方法进行了验证。
Due to the fact that the control rules are generally experiental in fuzzy control of structural vibraition, a method of generating fuzzy control rules through fuzzy modeling is proposed. Firstly, a fuzzy relationship model of structural vibration is established by making the state variables of the system equation fuzzy. Then, based on the analyses of fuzzy relationship model,the fuzzy control rule is generated for structural control. Finally, the numerical simulation of fuzzy control of a SDOF system is used to check the fuzzy controller.
