摘　　要：基于模糊控制原理,提出和构建运用于大型杆系空间结构的模糊控制系统和简化模糊控制器组成,包含模糊化接口、规则库、插值查询表等。运用该模糊控制器,实现对典型网壳结构的振动控制和数值仿真。对比分析采用不同结点的位移、速度作为双输入时的结构动力响应。研究表明,该简化的模糊控制器设计简便、易于操作、振动控制效果显著。Based on the principle of fuzzy control, a fuzzy control system was illuminated and the basic constitutions of the simplified fuzzy controller for spatial reticulated structures were constructed, which contains fuzzification interface, rules library, interpolation polling list etc. By using this simplified fuzzy controller, the numerical simulation and comparison for vibration control of a typical spatial reticulated structure were carried out, in which the displacement and velocity responses of different nodes were chosen as two input variables. The study indicates that this simplified fuzzy controller is effective in vibration control.
