摘要:
对3种采用不同隶属函数和模糊规则的模糊控制器进行了比较分析,即分别比较分析了采用相同模糊规则和不同隶属函数时隶属函数设计对动力反应的影响,及采用相同隶属函数和不同模糊规则时模糊规则设计对动力反应的影响.并对一装有磁流变阻尼器的5层结构分别采用不同模糊控制器进行了实例分析,结果表明:磁流变阻尼器输出大控制力并不能同时有效减小系统的位移和加速度反应,因此在模糊控制器隶属函数和模糊规则的设计中必须权衡系统的位移和加速度反应,以达到最佳减震控制效果.
Abstract:
Three kinds of fuzzy controller having different membership functions and fuzzy rules are designed and compared with each other. When the fuzzy controllers have same fuzzy rules and different membership functions, the influence of different membership functions designs on the dynamic responses are analyzed. And when the fuzzy controllers have same membership functions and different fuzzy rules, the influence of different fuzzy rules designs on the dynamic responses are also analyzed. A numerical example of a five-floor building structure with MR(magnetorheological)dampers is given. It can be concluded that strong control forces produced by MR dampers can not reduce structural displacement and acceleration responses at the same time, hence, structural displacement and acceleration responses must be balanced to gain the best vibration mitigation control effect when fuzzy controller is designed.
